I set all the valves at .021". Yes, the person was experienced. He is a reputable machinist and builds race engines from his garage!
I have had some problems with the SUs. I recently discovered I was running way too lean. Could this factor in? I am still dialing in the carbs. At this point, when I push the "lift pin" on the side of the carb up, the engine stumbles a little bit, but the plugs are a light tan. I also turned the engine over until #2 cylinder was TDC and the top of the piston was a light tan color. Is it still too lean or should I leave it there? The idle has gotten much smoother as the carbs are enriched.
