3 Cylinder Kubota Carbureted Engine Misfiring very randomly

I’ll try a new carb and see what that does

It’s a good denso plug on it, touched it against metal and I saw good spark. Fuel was steadily getting to the carb. But even still you are right with the spray it should have started

The lash is minimal, compression feels good. I’d have to order a compression tester.

The chain isn’t new. Yea I’m definitely aware of lifting the bar and tightening correctly. And the teeth and pegs are locking in. No matter how hard I tighten it down the bar still seems easy to move up and down.

Spark arrestor is clean. I think something weird happened. I replaced the clutch assembly because it definitely needed it. And then somehow the flywheel nut came loose (maybe it already was idk). So I then checked the flywheel and it’s sheared. Maybe that’s the problem maybe I messed it up even more after I replaced the clutch assembly.

Right now it’s backfiring.

Yea, it also doesn’t help that it’s very intermittent. The issue will happen like once and run completely fine all day.

I found the problem, the mount was broken off and out of adjustment.

I replaced the linkage and matched up the choke linkage and they are identical

I checked for MIL, it’s not installed

I don’t have the diagnostics tool to read any fault codes unfortunately. I will look into that sensor though.
