This carb was rich everywhere. At idle. Under acceleration. You name it, it was trying to drown itself. I only mention at idle because that's when my eyes were watering the most. Lol

These neighbors are from Monmouth CA which is at 7,000ft. We're now at 2800ft. I don't think they ever adjusted the carb while living at altitude, so this motor was trying to drink itself to death from the day it was installed. Their initial timing was around 9°-10° if I remember correctly. It was a dog. Once we leaned it out, that old girl was chooching!
