The head gasket is blown. Seen it blow oil out of the fuel pump a few times.

Remove the paper filter and replace it with the round red screen type. Some paper filters are not compatible with gravity systems.

The great ethanol vs non-ethanol debate rages on!!!! Just like oil, oil filters, spark plugs use what gas makes you happy. I have about 30 things with gas engines that all run regular pump gas and i have stored regular gas in cans for over a year. Never had an issue. I guess i am just luckier...

"When it stalls the only way to get it going is to disconnect the fuel filter and let gravity fill it up again." Does it have a fuel pump or is it a gravity system? Is the fuel filter the pleated paper element type?

Thanks. A very long time ago my father told me that something you have is worth what someone else will pay for it and you are worth what other people think of you. Took a while for it to sink in.

When i took it back she refused to let me eat the blown engine repair. We haggled and i said just pay for the parts and labor for the original repair and the parts for the blown engine. She said OK and then wrote the check for $50 more than that and gave me a hug. She lost her husband 8 years...

If it has the stupid automatic electric parking brake you might try unplugging and plugging in the connector to the brake control module a few times and see what happens. They are famous for corroded connections.

I have a 320 grit ball hone designed for cast iron and works well. I have used it on aluminum for a few seconds and had good results with regular rings.

If letting out the clutch kills the engine then that switch is working. Seat swith a better place to start.

It's a 4stroke. One will be impulse from the crankcase.

There was an article i read on the internet (must be true) that most of the plugs on amazon are counterfeit. I get my plugs from stens and another reputable online source. Took a plug out of a honda once that i was pretty sure was a counterfeit NGK.

I guess i am lucky. I put in close to 100 plugs a year most of which are champion. Haven't seen any failed plugs

I found the guy a used flywheel on fleabay for $100. Cheaper than wasting time with a maybe fix.

Yeah cust asked if i could fix the flywheel. Sorry. Used a hacksaw and a cold chisel to cut the stuff off then found it got up in the bottom bearing. So they get to buy a new spindle.

I have had the RJ19LM not work in some old tecumseh but the nonresistor version worked.

Customer did an oopsie! Then i get this fargon mess. Electric fence plastic string. Has stainless steel wire in it. Just another day...

The is3100z came in 2 varieties. The older ones, like mine, have separate self contained hydros. The newer ones have a single pump and separate wheel motors. Sounds like the OP has an older one with separate hydros.

Yeah fixing them isn't the issue. Give me a schematic and a parts list and i can fix most things. Did that for 40 years. Nothing special about the technology. Right now my favorite engine to work on is Chondas. I can get most any part now cheap. Just put a new complete chonda cylinder head on a...

You are breaking a 5/8 belt with a 6.5 hp engine. Something wrong here. Are the belts snapping or getting shredded?

Very true but it's just me.

"Kinda sounds like a battery power unit that I need to start researching before they start showing in my shop." I solved that problem in my shop. I don't take in any electric mowers. Every piece of equipment i have taken in has needed parts i can't get. I've spent so much unpaid time searching...

The owner is a lady i have known for 25 years and i just decided to fix it on me. Seems to be the right thing to do.

I assumed the rod seized but there was absolutely no aluminum on the crank. Yeah i think the piston got taken out because of the rod. Interesting, the parts list shows 2 different pistons depending on date code. Either one works. Only difference is one uses 2 wrist pin clips and the other only 1.

No. Didn't seem to over rev. Already tossed the rod. There was probably 30 small pieces of rod material. Engine was a 31R777. Lucky it didn't break the block. Did shear the key. I used a 240 grit ball hone to break the glaze and had to file and smooth a ding in the crank journal. Could have been...

9 year old mower came in for bad drive belt and broken hydro fan. Easy fix. Never touched the engine. Fixed the belt and fan and sharpened the blades. Fired it up and mowed for about a minute and BOOM. Rod, piston and gasket kit $150 and labor. Charged her for the belt and fan and i ate the...

But not as good as Scrub's. 😯 I guess this thread needs some pics of grinders.

Don't overlook a bad seat switch

Regularors need the battery to excite them to start charging. 8v should be enough. It does sound like a bad regulator

With a charged battery you should be getting approx 12v at the output tab on the regulator even with it not putting out charging voltage. How are you measuring the 8v? Battery charged?

With engine running and battery connected what is the voltage from ground to output tab on regulator? Is it the same as ground to battery positive?

You may have fried the stator. You should have approx 28 volts AC @ 3000rpm across the two stator wires going to the regulator. Unplug and check the stator output.

Hey rivets. I have a red mower that won't start. How do I fix it? 🤔😵‍💫😂😂😂😂 Looks like the the e405 uses that crappy little 4 stroke crapsman and trash bilt is using on all the small stuff.

From the parts list it appears the engine has plain flat tappets and not hydraulic. It will not be pumping oil up through the lifters and pushrods like a car engine. The engine lubricatethe valve train by splash and mist. If the engine is running fine and not seizing the rods on the crank...

I have used international red. It is pretty close.

If we are talking about a 5hp 13xxxx series briggs engine the "easy spin" bump is on the intake and not the exhaust. If the engine is not burning oil the most common cause of carbon deposits on the plug is not running rich but rather not running the engine hard enough to get the spark plug into...

Some use the D spacer and some don't. Not sure of your application but this is what it looks like https://www.ebay.com/itm/225955067246

Buddy of mine raced flat track back in the day with a big 2 stroke single. Once up to speed he held the throttle wide open all the time and used the compression release to modulate power in an out of the turns. Keeps the engine revs in the powerband all the time. Brakes? What are brakes? I...

But the real question is what condition is the mower in overall. I don't get that kind of price and Most folks won't want to put over $1k into an older mower. By the time I replaced the trans and belt and idlers and whatever else is bad under the machine I am over $1k. Then throw in the annual...

I've had a few customers want me to work on 100 series JD mowers with the "slows down on hills" death whine. I won't even take them in the shop. Local JD dealers quote ridiculous high price to replace trans because they don't want to mess with it.

It's not a stuck valve. If they stick it is always open. Pull side cover which is hopefully not seized on the crank. Pull the cam out and see if you can turn the crank.

The 632201 carb is for a HH70. Heavy Horizontal 7hp. Cast iron engine. I don't think they made a HH120 with tiller reverse but they did on the HH70. Can you get a Pic of any govenor or control stuff?

A cast iron HH120 would be a beast on a tiller. Probably a HH70 or a MH70 from the carb number.

Most likely either rod seized on crank or crank seized in case.

The compression release on this engine is simply a small bump on on the intake valve closing ramp. It will not stop the engine from turning.

This thread took a left turn a long time ago.

Are they standard 251's with no primer bulb or 251ce's with a primer bulb and EZ pull starter?

Get some straight 50 wt. Won't fix them but will help.

The new stator should work fine as long as you have the 20 amp regulator.
