Rich running engine
Posted by Daniel on 3/19/2013, 1:31 pm
After 10 years of body/interior work on a 72 GT6 that I bought on ebay, I got the engine running. Good compression but puffs of black smoke on acceleration. I suspect the problem is related to the carbon canister/crankcase ventilation system being too restrictive creating too much vacuum at the carbs. When I remove the oil filler cap, engine rpms jump up. Is this normal? What else can I try?
