Both plugs are pretty consistently wet and dark. Not the worst I’ve seen, but the motor is shaking like hell (like what happens if you set the slow speed needle way too rich) at anything much beyond 1/4 throttle.

I’ll report back tomorrow once I have another go at it. I’m sure it’ll get figured out by end of day. A little disappointing right now, I already replaced gearcase seals, rebuilt the ignition, and fixed the manual recoil today, after rebuilding the carb, the fun is seeing them run the right way again!

I will say on this one that when I pulled down the gearcase the lower main bearing oil recirculator pin, that was missing. Thankfully there was no rod knock on this motor. So perhaps the terrible condition it was in when I started the day in fact saved if from being destroyed, because since it couldn’t be run by the last owner or two, the bearings weren’t run lean and destroyed.

These 6’s seem to be prone to rod knock.
