spark plug

90 hours. I've never had to add oil. Plugs look a bit rich to me. FS600V. Choke fully retracted. Runs seemingly normal. No smoke (black or blue) when running or accelerating. Thoughts?

OK, I've picked quite a few weed ceaters, chainsaws, leaf blowers etc from yard sales over the years and I've been trying to get them up and running. First thing is to dump the gas, then check the sparkplug to see if theres any spark left in it.. Here lies my delima: Where ccan I find a good...

Kohler SV540S will turn but not run,changed everything new, head gasket, lapped the valves and gapped, carburetor,air filter,fuel filter,still not run. Shows 65 psi compression. Could it be timing problem.Have not opened engine itself. What else should I check.It was warm then suddenly stops at...

I just completed a repair on my Troy-Bilt XP/Kohler Courage 20 SV600 lawn tractor that required me to remove the speed control bracket. Now that it's all back together, the engine is running at a too-low RPM. it looks like adjusting the RPM is pretty simple but I'd like to use a tach to make...

Have an older Echo PB-201 hand held 2-cycle leaf blower about 2006 vintage. Runs great and going to pass it on to a friend who can use it. We have converted to battery because the Mrs insists on using a leaf blower and she has a bad arm and can't pull starters. So here is the question. The Echo...

Yes I am aware this plug is unusually wet, which makes sense as the mower wouldn't start. This is the machine that turned out to be overfilled with oil. But I'm only making this post to ask, what is the condition of this plug itself, not the motor overall. Besides behind wet, this plug looks...

I have a BVS 143 that needs a new spark plug. I have the owners manual, which has a diagram clearly showing the plug should have a reach of 8mm, and a gap of 0.6mm. It also states to replace the plug with a Champion RJ17LM plug. If I look up this spark plug is has a reach of 9.5mm, and a gap of...

I am using a multi-meter to determine if my sparkplug is not working on my Murray snow-blower. I cleaned the carb last year and it worked fine. However, this year when I pull and even when I use the Electric Starter, I cannot get it to work. Spark plug testing : from the videos I watched, it...

I have a Toro commercial mower 74180 and went to change the spark plugs. The rear plug was annoying enough because I had to remove the battery to get clearance to get it out, and the front is worse. I was able to pull the front plug, but could not thread the front plug to tighten it...

Hello, I have an older Toro Recycler 22” (20073) with a Tecumseh LV195EA (6.5HP) engine. It was my mower many years ago (6+) when I was responsible for maintaining our first yard. Then it sat in a shed for 6 years and has only run a few times over that span. Anyway, I’ve replaced many...

In the shop, I have a vintage Garden Way Troy-bilt beast. I performed a valve job and valve lapping (the exhaust valve was not closing, no power or idle), and the machine is in excellent condition, and the owner wants to restore anything and everything to get another 20 years out of it. Anyway...

have a kohler ch25 that runs but have noticed that power drops off, after running for a little bit compression is 125 and 115 one plug looks good but the other has the black soot on it could i have a bad coil on that side thanks

Greetings, I have a Gravely Professional 8 hp with an odd Kohler motor, apparently. The engine tag lists it as a K181, but Ive had better luck with M8 parts manual. Starting with the cylinder head, got the machine with helical coil for spark plug and it eventually popped out 10 years later...
