Re: 310 clutch upgrade

It definately has more power, but I am still sorting the Weber carbs. It is running very rich, plugs are sooted, tailpipe is black and sooty.
We broke the engine in, on track, with no real run in period. We ran it for 30 hours, under race conditions with no problems other than a set of soot fouled plugs and an exploded alternator( could not take the revs).I will change from BP6ES back to BP5ES plugs and rejet the carbs. More jets arrive this week.
It saw 8K on every lap, burned 105 gals of race fuel, and did not use any oil at all.
looking for jetting suggestions.
A15, 280 cam,GX head with 37mm valves, weber 40 DCOE carbs(33 mm venturies)
