Hi, so I’ve recently gone through my ‘75 as it was running on one cylinder, replacing the coil fixed that. I also put on a new (old) set of BS38s that I cleaned, just with carb cleaner and an air compressor.
So it starts first kick, but upon throttle there are flames coming out of the left carb, that I can see through the air filter… it is consistent upon throttle.
The mix screws are set to 2 1/4 turns out, they are 77-78 carbs so are to spec.
I went through the point gap, and valve clearances but haven’t touched timing. Could it be I’ve set one sides valve clearances wrong? I did notice the left side (flame side) exhaust was getting hotter quicker than the right side.
I couldn’t find any threads on actual flames coming out from the carb, it’s on every throttle at idle which is a bit concerning. It’s not backfiring, there is no sound, and any help would be appreciated!
