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.

Been there. Guy wanted me to change starter on a car. It was under the intake manifold.

If the cylinder is worn not much you can do other than new cylinder. May not be worth all the detective work as a P&C kit is only $35

If you google "jd445.pdf" you can download the service manual from garden tractor talk website.

If the belt pulley is not turning (power off) and the clutch makes a noise it is probably the bearing in the clutch. With the clutch powered on the bearing doesn't spin so no noise. I would remove the clutch and check the bearing.

Remove the deck belt Engage and disengage the clutch Does it still make the noise when disengaged? Does the belt pulley stop spinning when the clutch is disengaged? If the belt pulley keeps turning when the clutch is disengaged and make the scraping noise the bearing in the clutch is probably bad.

Most handheld 2 strokes have locating pins in the in the grooves to keep the rings from turning to where a ring end is in a port (bad). And the ends are tapered to fit the pins. I have never had to file rings. OEM or AM I just put new rings on the piston and install. Never had a problem. Not...

Check the tank for rust. If it has flakey rust the Houston we have a problem. The tubes are prone to cracking and are readily available. Did you replace the fuel pump diaphragm?

If you had the carbs off and apart have you synced the carbs?

Never seen a mechanical ACR on a multi cylinder 4 stroke bike. Honda did have one on the XL500S. It was a 500cc 4 stroke thumper that pretty much killed off the 2 strokes used in flat track racing. Back in the heyday of big single racing 2 strokes it was common to have a compression release...

Anybody who had a big 2 stroke single knew how to "straight leg" start a bike. Work the engine around to the compression stroke. Shove yourself up high enough to extend the leg on the kick start out straight and drop your body weight down on the straight leg. Trying to start it sitting on the...
