Talked to Tom last year about possible new jets and he seemed awfully offended that i asking about changing the jetting. He said the stock jetting setup is always perfect.
Complete shot in the dark:
Does Langdon know what kind of manifold you're running? There are a number of folks here who seem to run that setup very successfully, but I'm guessing vast majority are using one of the more commonly available Offy or Fenton intakes.
Looks like you have something a bit unique. Is it an Edmunds? Perhaps the various two carb manifolds have different flow characteristics?
