Tach! I have a problem with my Holley carburetor (R84014-1 650cfm). I have mounted the carb on a freshly reconditioned Chevy 5.7L block. Now the problem is that the car is running very fat. And that was so fat that my chrome bumper was black after 10 minutes drive. The engine is running quite well in the stand, while the ride, on the other hand, it jerks, and has far too little power. If someone has a tip like me to buy the carburetor without a jet set for 100$, a little lean frame t? MfG Daniel
