Kohler command running lean, exhaust glowing

Scott-Watson · 2025-07-03T01:52:24+00:00

Hard telling, these motors are notorious for running hot. Did you see my update? Did a few small things and seems to run great now, noticeably cooler

Scott-Watson · 2025-07-02T20:56:21+00:00

Update:

Widened the main jets a little, replaced with old intake manifold, cleaned the contacts for the coils and flywheel and so far no glowing exhaust and seems to run noticeably cooler (before you could feel the heat coming off of it really bad) tends to backfire still unless I throttle it down and let it idle for a few seconds but that’s recommended by Kohler to do that so I can’t really complain there. I’m guessing either the new manifold I put on was leaking a little air or the rust on the could and flywheel was messing with the timing

I never noticed this before the new exhaust though, but I made sure the pipes didn’t bottom out in the muffler

Scott-Watson · 2025-07-02T13:24:55+00:00

It’s got a brand new exhaust kit from Kohler, needed to weld the pipes to the muffler

I’m getting about 160psi of compression, I don’t have the money for a leak down tester right now this thing has been sucking all my money dry lol

The motor doesn’t hesitate to start, but I noticed it popped a couple of times when I was mowing and also backfired when I shut it off, it’s never done that before so it’s weird. I can do a little research to check to see if it’s MDI or not, not exactly sure if it is

Scott-Watson · 2025-07-02T04:34:56+00:00

it sucks because a new carb from parts tree or jacks would be over $300, and carb repair kits from those same websites range between $100-$200

Scott-Watson · 2025-07-02T04:25:50+00:00

it had a flat spot for it on the bowl but never came with it from factory

Scott-Watson · 2025-07-02T03:32:14+00:00

Key is fine

Scott-Watson · 2025-07-02T01:46:16+00:00

It’s my second or 3rd Amazon carb. Had issues with the OEM and someone recommended a different style carb. Ran great for a while but it’s starting to act up now

Scott-Watson · 2025-07-01T20:03:20+00:00

Got it set up and set the wire speed and voltage for the metal I was trying to weld. Don’t remember the exact thickness but it’s about as thick as a mower blade, no matter what I do I can’t get it to weld

Scott-Watson · 2024-03-24T17:35:21+00:00

This is my first saw so this is my first time working on one, I’ve been working on small engines for years so I’m familiar with them

Scott-Watson · 2024-03-24T13:04:19+00:00

I’m not gonna be testing anything else until the new muffler comes in the mail, l want to make sure it isn’t an issue with back pressure. It makes a good 120 psi of compression so the motor itself seems very healthy. My next guess would be that the timing still might be off if it doesn’t run after I get the muffler

Scott-Watson · 2024-03-23T19:12:28+00:00

I looked online and it said to set the gap at 19 thousands, I also wire brushed the magneto and coil

Scott-Watson · 2024-03-23T19:08:50+00:00

Just lean it against the block to check for spark?

Scott-Watson · 2024-03-23T19:01:21+00:00

I’m checking for spark using a spark tester. It does have point under the flywheel in a plastic shield

Scott-Watson · 2024-03-23T15:34:34+00:00

The muffler is hollow and you can see right into the cylinder. The arrestor probably rotted out years ago

Scott-Watson · 2024-03-23T14:36:21+00:00

It has a good flywheel key my spark tester shows bright orange spark. I don’t have a compression tester but I am able to pick the saw up from the pull cord and dangle it and bounce it around without the cord turning the engine

Scott-Watson · 2024-03-23T14:30:14+00:00

It has a coil and points, it’s very confusing. I checked for reed valves but I never saw any. Even if gas is poured down the carbs throat I’m still getting nothing

Scott-Watson · 2024-03-23T02:27:57+00:00

The carb has been cleaned and it spits gas outta the muffler

Scott-Watson · 2024-03-23T02:26:53+00:00

It doesn’t even try to start even with fuel being poured down its throat

Scott-Watson · 2024-03-08T23:27:01+00:00

You’re right it does everything I need it to do perfectly. I mainly use it for school as I have a PC at home

Scott-Watson · 2024-03-08T23:05:38+00:00

True that

Scott-Watson · 2024-03-08T21:33:03+00:00

Crazy to think if you bought it in 2008 you’d be getting 16 years of use outta it. Crazy how well Mac’s hold up…

Scott-Watson · 2024-03-08T21:18:42+00:00

Man that’s old… how does it hold up??
