Center carb. After the light goes green, it depends on the traction and power. What setup do you got?

I'd say nothing to worry about!
 But seriously, on any manual tripower's I've owned - even stock ones - holding the secondaries open with the clutch disengagaged would hit redline in no time.. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
