What do you want to get straight on it? Tell us more on your combo. What brand dragster, is it suspended, what motor, gear, tire, carb or injection, converter, etc.

I can tell you we have a 2010 Racetech swingarm. Weight is 1985 lbs with driver. 582, 1250 rupert alky carb, 4.10 gear, 34.5 tire with 6600 converter. car will 60 foot 1.08-1.10 depending on where we go. Runs 4.70-4.80's and runs 7.50's to low 7.60 at 177-179mph.

I believe my carb is a 3 circuit 1250 from George. His stuff tends to be real fat on the idle circuit. I want to say my 1250 has 161 jets in it. I went to 170's and it moved around. Dropped it and it is stuck.

hammertime

need to drop it 10 and call it good, Ruperts dont care for a lot of jet. Of course take a drill bit and make sure its actually a 180 jet

Dave is correct. George does not typically mark his jets. If they are marked odds are someone changed them.
