I have a Harbor Freight Leakdown Tester. But being honest I have never mastered it. I can pull the head off and I could take the breather off to view the valves and springs. From there I can get a look at both ends of the valves and see how sloppy the guides are. Let me know if you have any...

I looked at an IPL last night and a light bulb came on that this L Head does not have a separate valve ate of the head gasket. The valves on this style of engine are exposed to head pressure and not secured by a section of the head gasket..correct? So a blown head gasket would not cause oil...

I like your take on ‘A good learning experience’. With this being a L head and looking at the shape of the head gasket it does not seem that a blown head gasket would cause oil blowback like a OHV engine which has a separately secured valve section of the head gasket. This is just one large...

Not sure of your carb but the SRM225 trimmer carb has an adjustment screw hidden by a small plastic cap. Cap needs to be removed to get to the brass screw. Once the cap is out you can open or close to get better performance. I gave found In some cases just moving it a turn in or out and...

Have you replaced the fuel pickup/fuel filter? I have had 2 cycle trimmers that would not run right until I replaced the fuel filter

I am helping a neighbor with a 12.5 hp Briggs vertical engine 289707 1179E-3 020503ZD. It is a single cylinder L Head design. It does not have a Nikki carb. The engine had no oil to speak of when I first checked it. The oil sump was full of gas. I drained it out and refilled it with oil. I...

So I got into the Timemaster today. I found that the underside of the mower was quite caked with hardened grass clippings. I scraped and power washed it including the transmission and transmission output shaft. When I got done cleaning it I ran it and the screech was virtually eliminated. It...

Good point Nobody replaces just the one shoe that the heel fell off of…you get a new pair

Do you suspect both bearings would be bad? I see there is a 3rd bearing in the center that supports the shaft is that potentially an issue?

I stopped at his house and shared the sad news with him. He took it well and said he has a line on another used JD for $400-$500. I told him that he’s 2 for 2 on killing tractors from lack of routine maintenance… not rocket science. I strongly suggested he do better on his new-used tractor

I just acquired a 21199 serial 4008… The guy I got it from said he was trying to fix the transmission. Problem being a loud screech when the transmission is engaged. He said he replaced the belts all 3 of them and it did not help. His take was that the transmission needed to be replaced and he...

I am going to have a heart to heart talk with the neighbor, He bought this John Deere used a few years ago after he tied up the engine on a Husqvarna tractor with a Briggs on it also due to lack of oil and general maintenance. I would have thought he would have learned his lesson from that...

Rivets. Thank you for the manual! I am digging into right now Hopefully I will learn a thing or two, and avoid asking too many dumb questions Spit

I was looking at parts breakdown o -line and I see 2 different part numbers for cylinder heads 24 318 105 S and 24 318 113 S. One is I identified as #1 and one as #2. Is there a left and right hand head? I was unable to determine which is which. I only saw one Head gasket 24 841 02 S. So I...

I am looking at a neighbors John Deere L130 It has a Koehler CV23S 75569 engine a V Twin style and according to the tag on the blower housing in was made April 13 2004. What I found was the engine would not start l sprayed some starter fluid into the carb got it to run. I found it was very...

So I got the old valve keeper installed and had trouble getting it to run. I set the valve lash 3-4 times at .005 both valves. I must not be savy enough to get it right the 1st time. Anybody want to share their process for setting valve lash on a OHV please do so. I let it sit for 3-4 hours...

I redoubled my efforts and searched the area where the keeper flew into..and I found the original keeper. It fits the valve perfectly. The original does not have the projections, whoever suggested that those needed to be filed or dremel-ed away was correct. I am going to use the original and...

No it will not fit into the smaller hole outside of the head…it is just too small of an opening. If you see the photo the placement of the smaller hole on the keeper it is not allowing the full 4.8 mm circumference valve to pass into it. I do not know who I could check with at Kawasaki to...

Correction: the most narrow part (the gate way between the larger outside hole and the center hole) of the center hole is 4.1 mm not 5.1... If it was 5.1_it would fit in I think

No it will not fit into the smaller hole outside of the head…it is just too small of an opening. If you see the photo the placement of the smaller hole on the keeper it is not allowing the full 4.8 mm circumference valve to pass into it. I do not know who I could check with at Kawasaki to...

I am attempting to repair an old Ferris 36 inch walk behind. It has a Kawasaki FC401v engine. I removed the head and found both push rods not in contact with the rocker arms, and that the exhaust valve was stuck. I removed the head and removed the exhaust valve cleaned up the valve shaft and...

Thank ms to you all for your input. I was hoping that given the good condition of the piston & rings and the cylinder, I would be able to replace the broken rod and be back in business. Then I noticed the scoring on the crankshaft from and lid. I knew I should get input and advice looks like...

Not to confuse things but here are a few photos of an old crankshaft that I think is fro a Honda with the same type of damage to the crankshaft

Here are some photos of the upper bearing surface on the crankshaft and the damaged cast aluminum bearing surface in the lid. As I think I previously mentioned I have not disconnected the blade clutch and transmission pulley or removed the engine in order to remove the crankshaft from the...

I will do that later this afternoon. I put the engine back together so I would be able to remember how every thing went together. When I was posting the photos off the shattered connecting rod I was kicking myself for not taking photos of the lid and crankshaft

Thanks to everyone for your input. This is one heck of a mower with a cast aluminum deck and is in great condition. The concern that I have with the crankshaft is scoring not on the rod journal but at the top of the crank where it passes through the lid. Of course the lid bearing is just a...

I am working on a John Deere JX75 a 21 inch self propelled mower approx 25 yrs old it has a Kawasaki FJ180V-AS11 engine. The connecting rod broke. When I opened up the engine I found the cylinder and piston and rings to be in great shape. The connecting rod journal on the crank looks good no...

yes it is at least 30 years old. The piston and rings as well as the cast iron cylinder sleeve look great. I have not pulled the crankshaft completely out of the engine so I have not seen the lower bearing surfaces on the crankshaft or the sump/bucket look. Also I haven’t been able to...

I have a JX75 with a broken connecting rod. The piston, rings and cylinder look great. The upper bearing surface on the lid of the engine and the top of the crankshaft that passes through the lid/ bearing are both scored. I am asking for input as to how smooth both surfaces need to be…and how...

I am having no luck pulling a Honda CGCV190 flywheel. I have tried a 2 leg puller with out any success. I am thinking that arms on my claw type puller squeezes the top of the flywheel and is not pulling straight up enough. I have ordered a 8 inch puller that gas straight arms and will allow...

Is it OHV? Adjust the valves?

I am impressed how politely answered this question was. It is very very impractical if not totally impossible to convert economically from gasoline to diesel fuel. Like someone said if you have an unlimited budget…have at it

One more thing…sometimes the carb gets so cruddy at the inlet that the float needle sticks and gas cannot enter the bowl. If you remove the drain bolt with the gas shut off open the gas should continue to run through. If only a small quantity of old crappy gas comes out and it stops, your...

I just looked at an IPL for a version of your snowblower. Keeping in mind that the PR241 model is like saying it’s a Ford Mustang when what is needs is a VIN number to get exact parts. There is a much longer number that begins with a 9 that is needed for exact parts matchup. All that said it...

Is this a Honda style carb with two bolts on the bottom of a metal bowl.? If so there is a brass orifice in the center of the carb. It will require a very fine stiff wire, insert the wire up through the orifice and make sure it is open. The wire should be able to insert a full inch to inch...

If there are 2 bolts on the carb bowl. The one at a 45 degree angle is a drain. If there is, remove that bolt and drain some gas out. Catch the gas in a clear container ( old jar?) See what that it looks and smells like. It should be clear and should smell like gasoline not like varnish or...

Have you removed the spark plug and replaced it with a new one or a known good plug? Also try adding some gas through the spark plug hole… replace the plug and attempt to start it. If it pops and runs even for a few seconds you know it’s a fuel delivery problem. I should have asked if the...

So I am not going to get a chance to try to fix this.. my friend called me and said the dealer had called him back and said that when they were looking at his records, they looked at the wrong blower and this blower was in fact under warranty. So he picked it up and is returning it to tge...

I hit the wrong button and sent the above before it finished…. So to get back too it I had the muffler off and cleaned the spark arrester screen and there is nothing wrong with it. I attempted to look at the piston through the exhaust port but it seems that this engine is the Stihl 4 cycle that...

I am attempting to repair a BR700 backpack blower for a friend. My friend brought it to me saying he had it looked at by a local Stihl dealer..who told him it was tied up and needing major engine repair. I removed the spark plug and put an oz. of ATF and a little gas in the spark plug...

Hello I am working on a BR700 backpack blower. A friend brought it to and it was tied up. Rope would not pull. Took the starter off and removed the spark plug and added an ounce or so of ATF-4 and some gas. Worked the crank back and forth a few degrees at a time and it began to move freely...

Yes I misspoke it is acetate. Thanks

Not to answer my own questions. But I just watched a YouTube video on the subject of pump diaphragm materials. I found it searching in my YouTube app ‘Walbro Carburetor Diaphragms’. The guy who did the video identified 3 types. Rubberized which are black and rubbery, Acetone which are the...

I did think it was odd that the lever and spring were not included. I reused the old ones… not ideal. I was thinking that I had read somewhere that the synthetic pump diaphragms, like the electric blue colored one were an upgraded version and replaced earlier styles if they match are the...

Thanks to everyone for their help! After talking with the Echo tech who had nothing good to say about aftermarket carbs; I purchased a k10-WLA rebuild kit and rebuilt the original Walbro WLA-1 carb with an actual Walbro kit. Lo and behold it fired up. It ran poorly and I was able to adjust it...

So I went to a local small engine shop who has a tech who really knows Echo. I was not able to speak directly to him since he was at lunch. The owner shuttled back and forth from the lunch table to the front counter and asked him about my problem. I brought my tablet with a pdf of the IPL...

It has a choke lever on the air filter box. The part on top of the carb echo calls an air valve assembly and it opens and closes via a link based on the throttle position and it fits into another part called a valve assembly. This 2nd valve asby is attached to the cylinder and 2 air hoses run...

I have a PB-500T. Serial P31212136027 I can get it to start if I pour a small quantity of gas into the carb. After it starts it runs great full throttle and low idle. If I do not pour gas into the carb I can prime the carb ( a dozen pumps or more..full choke and pull, pull and pull some more...

I am thinking that I will have to pull the cylinder head. I will try pushing on the valve first. I am wondering if the valve sear on the intake valve came looseand has the valve jammed in the open position. If it is that...can I use the same procedure I have done on a few Briggs engines of...
