All the information is in Cliff Ruggles book. He sells complete rebuild kits and can recommend correct jet/rod combination for primaries or secondaries. His book has recipies for mild, performance and race applications.

 

Thanks, i have asked Cliff and he had no notes on these carbs.
Thought someone at this board would have noted the specs on these carbs?
