I have never used any fuel additive and have never had any problems starting in the spring. I shut the fuel off and run the engine till it starts to die out then I apply the choke and let it run till it dies and that probably gets all of the gas out of the bowl. I have unplugged a lot of...

Whether you weld it or plate it you are going to have to take some stuff off in order to get to the break. In my opinion I don't think a one inch strip of metal on each side of the break would be enough. You would have to use some small bolts and I don't think they could handle the pounding of...

If the hole is 7/16 of an inch or smaller you can use a plug-n-patch. It's a patch with a stem on it. You have to take the tire off and you pull the plug thru the hole then the patch attaches to the inside of the tire. Being a lawn mower tire the hole could be bigger than 7/16 because you only...

I'd say your needle valve isn't closing. The float could be full of gas or have a hole in it or stuck and it could be that something is between the seat and the needle valve. Was there a lot of crap in the bowl when you took it off and cleaned it?

I had an engine with a bad coil and found one that fit but was originally matched to a smaller flywheel. I put it on and it ran. I never did put it to use so I don't know how long it would last.

I had that problem with my Khroler engine. It had an oil leak and puked oil all over it and then dust and grass collected on the cooling fins and it would over heat. I took the engine out and fixed the leak and cleaned the engine and then it would shut down when the key was turned off. So my...

LOL. I never knew the family dog produced more pollution than a lawn mower. I probably push more pollution out my donkey every day.LOL!

I took the crakshaft seals out and then slid them over the caranksahft and they were very loose so they probably were allowing air to be sucked in on the up stroke. I put new seals in and that stopped the engine from puking oil out the vent pipe.

Here is one with your part number on ebay. He wants $19.90 for it pluss $29 shipping. It's supposed to be NOS and is in Hong Kong...

Actually the oil is blowing out the tube coming from the breather so it's not plugged and I had the engine apart and put a new piston and rings in it . The oil level was correct and probably a little low as it has been blowing it out. Would you go into a little more detail about how the fuel...

Walt, would that go for crankshaft seals too? In the earlier post I just said crank seals. dana

OK. Thanks Star Tech.I will try the leak test. I have the engine back on the mower. I'll put it in high gear and set the brake and hope that it doesn't take off out thru the garage door, LOL. I'll start of with low air pressure first. I have to say one thing about this OH160, I've never seen any...

Star Tech. I have a question about your comment here. I have a thread about getting a steel pipe out of a 1973 Craftsman Surburban with a Tecumseh OH160 head. I got the thing running but after it runs a few minutes it starts blowing oil out the vent tube. I asked the head man at the local Cub...

OK. Thanks StarTech.

At max RPM, have you held the throttle still in one position? If so does it still make that popping sound? It soulds like it is popping back thrun the carb like a burnt or leaking intake valve.

If the clutch was drawing say 10 amps would that burn out the 5 amp PTO switch or does it have a circut breaker in it? I'm thinking if ironhead did run a wire from the battery to the clutch with a 7.5 amp fuse in line that would definitely tell if the clutch was the problem or not. Can you see...

When I'm done mowing for the season I shut the fuel off and when it starts to run out of gas I pull the choke out it to suck even more gas out of the bowl and haven't have ANY issues.

When you checked the flywheel key was it smooth on all 4 sides? You may have possibly hit a small stump and distorted the key as it tried to shear and knock it out of time. Try a new key..

You need to take the bowl off the carb and see if the float is free to rise as the gas fills the bowl. If it free then the problem is with the needle valve not closing and stopping the flow of fuel.

That is what my breather looks like. I blew in on the breather hose and it had some restriction to it. I thought it probably should have had more restriction. I have had the breather mounted with the drain going both ways so I didn't think that would make a difference. It had been on reversed of...

My carb says Walbro on it and it has the adjustable main jet bowl nut and yes the fuel pump was screwed into the carb. It wasn't working right and I'd had it apart a couple time so I just took it off and let gravity pump the gas . When the fuel level gets down a ways and I'm going up a hill...

If it was exposed to a hurricane you may have gotten water in the tank. Water will lay on the bottom. Have some one rock the mower while you look in the gas tank and see if you can see any water moving in the tank. When you checked the pump are you sure it was gas coming out and not water?

With you knowing it was a 143 number you have been playing with this stuff for a while. It is 143 640012 and serial # is 3166E.

THE ONLY NUMBERS on the engine are the Sears numbers. There are no Tecumseh numbers. I started the first sentence a few days ago and never posted it and was surprised to see it still there. I was able to get the pipe out of the damaged head and it brought the aluminum threads with it. The good...

Will it run just as well without the weights as with? Did you ever put one back together with the weights?

I've taken a lot of small engines apart. I was really impressed with this OH160. It ran for 49 years till it dropped the exhaust valve seat. I think it's really built strong and I've never seen a small engine with tapered roller bearings on the crank shaft. My OH160 has 2 counter weight gears in...

ACF. The reason suggested cleaning your engine off is because I bought a used Toro with a twin cylinder Krohler engine and it had an oil leak and the oil collected a lot of dust while leaking oil. I'd be mowing 3 or 4 hours at a time and if I didn't let it idle to cool off some it would set...

I believe over heating can cause it to run after the key is turned off.. Clean the dirt and crud off the air fins and see if that fixes it.

I have a 1973 Craftsman Surburban with a Tecumseh OH160 engine. The seat for the exhaust valve dropped out of the head. I have another good head. I need to exchange the steel exhaust pipe from the bad head to the good head. Do any of you have any ideas on how to get these pipes out of the...

You should be thankful you aren't putting diesel fuel in your car. $10 wouldn't even get you 2 gallons in some places!!

I have a John Deere 400 the only numbers I can find on it is a Product Identification Number C400l 192567 M. It is spaced out like that. It needs transmission fluid. It is red so I assume it is ATF. Do any of you know which kind of fluid it would take? I think the mower may be from the...

I replaced the fuel line to the fuel pump and cleaned the cooling fins and it still quit running. Today I took the carb off and opened it up and it looked pretty clean inside. I blew compressed air thru the passages and ran small wires in all the little holes and took the fuel solenoid off and...

IT SOUNDS LIKE THE TIMING IS OFF. If timed right it will run without a carb just by spraying starting fluid in the intake. Possibly either the crank or cam shaft has 2 marks on it

Thanks for the replies. Rivets...........The engine is an 18 HP twin cylinder Kohler. Engine Info--- Family SKH624U1G2RA,,,MODEL CH18S,,,SPEC #62579,,, DISP. 624CC or 38.078 CID,,, SER.#273241450T I replaced one of the coils 3 or 4 years ago. It had a weak spark and the exhaust temp was...

Attached are a couple pictures of the wired thing on the back of the carb. What is it?

When I went to start the mower this spring the fuel pump would not prime the fuel system. I had to pour gas in the carb and start it then keep pouring gas in till it did fill the cab bowl. I mowed about half an hour and it quit running. It wouldn't start then I choked it and it started. Then it...

These bulbs just recently burnt out. I know they didn't get wet because I never leave it outside and I doesn't mow in the rain. Yes the lights are always on when running. The mower is a Toro/Wheel horse 518XI, Model # 73470 and serial # 8900769. Thanks guys...

I have a Toro/Wheel Horse with 18 HP Kohler engine.I bought it used and have had it about 3 years and the battery light has came on and off ever since I've had it but have never had any issues with the battery. The last time I mowed, a couple days ago, I noticed the battery light stayed on all...

My engine is a HH70-140038C and both magnets had come off and were stuck to the coil. I can tell where one had been glued to the flywheel there's no rust. The rest of the inside of the flywheel has the same amount of rust all the way around it so I can't determine the exact location where it...

My Toro 518XI mower has a Kohler engine with a problem, engine Info--- Family SKH624U1G2RA,,,MODEL CH18S,,,SPEC #62579,,,DISP. 624CC,,, SER.#273241450T. It is loosing a lot of oil. I fixed a leak last year at the cover over the breather reed. Toward the end of the mowing season the top of the...

Hi I'm Dana, the latest Buckeye to show up here. I've got a 73 Craftsman I believe they call it a Suburban. I've run it for 43 years and it has a good appetite for oil now but still runs good with a 42 inch deck. I mow about 4.5 acres and bought a used 98 Toro with a 60 inch deck to reduce time...

You can check the engine to see if it will run by giving it a shot of ether. I have started them that way without a carb but it won't run long. If it does run you could pour some gas in the carb and it will run a little longer and maybe be able to check the transmission. I have bought several...
