George Rupert Carb question
 
I just purchased a turn key dragster that is running an George Rupert Carb on a 598. My question is the jetting the same as a gas carb? Reason I ask is that I know that if I was going from a track that is 2600 ft corrected to a track that is 4400 ft, I'd drop the jet sizes two sizes with a gas carb. The carb currently has 172's and the difference in track elevation between what it used to run at and my track is approx 2000' but our humitity is probably 10- 15% higher. Just leave it and run her or drop one or two sizes?????

I don't run alcohol and never have with a carb, but I know a guy who has a Rupert carb on his dragster. He asked the same question and George told him "don't touch it".......I'm sure others here can tell you how far to lean it.
