Dieseling is usually caused by either carbon buildup that is very hot from a hot running engine or more likely overheated sparkplug tip from either the wrong heat range plug or very hot running engine. What does the plug look like?

Dieseling and running on (fuel solenoid off but ignition still on) look totally different. Dieseling from a carbon hot spot or over heated spark plug electrode results in engine operating erratically and usually making some off knocking sounds. With run on the engine just slows down and dies...

I have a STRUCK tractor on the shop right now with a OH140 on it and i have a 70's Sears suburban in the barn with a OH160 i want to restore. I have a HH120 on a Sears ST12 i blow snow with and a VH100 on an old Bunton walk behind. I really like the old cast iron tecumseh stuff.

Yup! If you have olders stihl stuff like chainsaws most OEM parts are NLA so aftermarket is the only option. Many a good saw has been kept off the scrap pile because aftermarket parts were available. OEM is great if it is available.

What is the engine model number? Can you post a pic of the spark plug and what is the numbers of the plug? When you sad dieseling is it running on when you turn the key off or just kicking backwards once when you turn the key off?

I agree that you should run an engine at the recommended RPM but back in the day of stock class WKA go cart racing we took the governor gear out if 5HP briggs engines and ran them for a full season at 6000 RPM with stock everthing except the oul dipper as the stock one would break. The one thing...

I believe they have opened an investigation into all these matters. That knock at the door will be the FBI.

Does it have a mulching plug or is it side discharge? Contrary to what most homeowners think gator type blades are not mulching blades. If side discharge you might try some high lift blades.

What blades are on it?

A snow blower mounted on a lawn tractor should have thrust bars that mount somewhere on the frame near the rear axle. I have seen some of the newer stuff that mount the blower to the front of the frame and entire frame gets twisted when the blower gets used like a snowplow. The snowblower i see...

Everybody has their way of doing things and if it works it's not wrong. At 65 with a bum shoulder, arthritis and trigger finger in my right hand pulling a starter rope is not my favorite thing so i do use starting fluid a lot for testing.

Is that kohler fuel also known as liquid courage? 🍹

I had a guy tell me that starting fluid would blow up an engine. I disconnected the fuel pump on a briggs OHV twin and gave him a can and told him to try and blow it up. He used the whole can and couldn't blow it up. Been a fun thread pursuing an urban legend. What's next? Does a mower run...

Thanks. I have been using the highflow HF303. And yes, i have seen the problem with filters bottoming out on the plate.

What filter do you guys use on the loncin toro engines?

Carb cleaner works. Just looking for a first hand experience. When i was in high school i saw my neighbor literally blow the air cleaner off his 327 impala with starting fluid when it was below zero one morning. Then he got it started and it ran fine. Scub needs a 🥤to go with the 🍿

Just looking for a first hand experience. What is the stoichometric ratio that makes ether explode? The speed of deflagration between gasoline and ether is not that different. You only get so many oxygen molocules in the cylinder.

😂

In a petrol engine it can and that is a CAN cause preignition which as we all know can blow a hole in a piston in a single cycle It should not be a problem with side valve engines but can cause problems with higher compression OHV engines No offense but "it can" but i have never seen it and i...

Not buying it. A "Some guy said" i have heard tons of stories but have never seen a first hand damaged engine

I was trying to use brake cleaner and got frustrated then saw the can said "non-flamable".

I have noticed that every time someone suggests using starting fluid as a troubleshooting tool people are quick to caution that they can "blow the head off" or "bend the connecting rod" or "bend the valves" or "blow it up". Over the last 50 years i have used starting fluid in literally many...

If you can do a cylinder leakdown test. Especially check intake valves for sealing properly. A bad intake valve on a twin can cause poor running and fuel to be spit out of the carb.

Lots of commercial guys have lift pedals. They use it when curb hopping or going over sprinkler heads and the like. They use the lift pedal while mowing to save time.

I have the cheaper HF lift. It won't lift most zero turns or larger lawn tractors. I quit using it when i nearly had it collapse on me with a mower on it. I have this one now. https://www.zoro.com/shinn-fu-lawn-mower-lift-hydr-750-lb-cap-wp0848/i/G8521877/ Haven't found a Z it can't lifft and...

Ferris recommends engaging blades at WOT and mowing at WOT. But what do engineers know (sarcasm)

Some kohler's idle fast because the linkage won't close the butterfly all the way. You have to loosen screws and move the entire linkage plate assy to adjust it.

A friend of mine had that problem with a mtronic MS362 saw. Dealer fixed it but would not tell him what was wrong with it.

Should change the name to "All Star Tech" with all the info he has and provides.

That'll buff out

Without a schematic and knowing EXACTLY what he did to the wiring everything will just be a guess. From what you describe the pto worked fine till he worked on the wiring. We have no idea what he has done to the wiring. He "thinks" the module is bad. Kind of a red flag to me.

One wheel motor for sure. Metal shavings in a hydraulic system is a recipie for real bad news unless every part of the system is flushed cleaned and checked. If it is a single pump and 2 wheel motor system and shavings are in the reservoir if you are lucky and there is a spin on filter between...

You need to remove every hydraulic line and flush them and then pull the pump and motors and check them. Does the system have a separate filter? You have one bad wheel motor for sure.

I thought i was bad. I drink a pot a day. And then today had to go to the JD dealer so i stopped at the speedway for a 24oz coffee.

If the mower has an auto choke it sounds like it is closing on a hot restart and flooding the engine.

That's what's fun about new mowers. When fuel injection works its great. When it doesn't it's not so great. From what you describe the engine is good mechanically it probably has an issue with fuel or spark which is controlled by the "box". You have inputs to it and outputs from it. Is it a...

Either needs more or less caffeine. ☕☕☕☕☕☕☕

Yes, you wipe it down after you spray it on.

"My oil is better than your oil" Just saying.

If a 2 stroke is flooded the easiest way to clear it is to remove the spark plug and turn the unit so the top of the cylinder is facing down and pull the cord about a dizen times. Gravity will help clear fuel from the crankcase.

Thanks. Appreciate it👍

Bert, you have no idea how FUBAR tax rates are in the US. Each county in each state sets their own rate. In the county i live in has a fine arts sales tax added in to support theaters in the county as an exemple

One is designed for small engines the other is for automotive but has the schrader valve at the end of the hose. Both readings from the same chainsaw

You have a primary or secondary compression problem.

Are you showing sales tax as income? I don't think i follow you. My accountant has me show parts and labor i charge out as income i then add the 7.5% sales tax that is not included as income. If i paid sales tax on a part i do not include that in what i charge tax on to the customer. I don't...

I setup a tax free account at o'riley with no problem. Guys there are pretty cool and don't mind helping me.

Stens did that to me starting in 2022 but a phone call fixed it. So far their customer service has been pretty good.

No, it doesn't

WD40 works great to clean and shine up a mower. Some degreasers can damage black plastic parts. I buy it by the gallon and have it in a spray bottle and i spray down customer equipment and wipe it down. It has a very mild solvent that cleans crud and doesn't hurt paint or plastics. Shines up...

What part of SW ohio? Go Buckeyes

I have seen E10 gas cause the o rings and diaphragms in cheap AM carbs to swell up and stop working. Try a little carb spray and see what happens.

No, electric pump cant leak fuel into crankcase. Must be something else

I call them high end residential mowers. On par with the JD homeowner Z mowers. I don't know any commercial guys who use them around here.

Diesel engines will have an injector pump and a lift pump that pushes fuel to the injector pump. The lift pump will be mechanical or electric. Usually fuel in the oil is a bad mechanical lift pump. Example https://www.amazon.com/Kubota-Fuel-Pump-Diesel-Engines/dp/B07RWFB42N

If the engine has a mechanical lift pump check it for a bad diaphragm.

Check the flywheel key.

Wow, i buy my plugs in shop packs from stens and i have installed a few hundred over the last few years and none have failed. Is it possible you got counterfit plugs? Many thousands of new engines come out every year with champ plugs in them that don't fail. Briggs has their own part number for...

Sounds like carb is vapor locking from heat. When it does it spray some water on the carb to cool it and see if it will restart. If it is running hot most causes are, too lean, clogged cooling fins, not running at full throttle under load, retarded timing.

When champion moved production to south America they had problems with plugs arcing intrernally but that was resolved years ago. I put in over a hundred champion plugs a year in mowers without any issues. But i still like NGK BPMR7A in chainsaws.

Not sure how true it is but "I read on the internet" that the xc plugs were designed to be a "greener" plug as they are designed to last something like 3 to 4 times longer before needing changed due to eroded electrodes. Mower ignitions are so low energy i rarely change a plug because it is worn...

Yeah, best i can research the center electrode has different inductance and resistance due to the alloy used and is harder so it lasts longer but the still will foul the same as the RC plugs. I have swapped in the RC12YC plugs in a couple dozen engines and haven't seen any difference. The $2...

I have replaced the xc12yc plugs with rc12yc plugs with no issue. As far as i can tell the xc plugs are designed for a longer change interval because the electrodes and a different alloy. I have not seen a difference in performance.
