Carb Help Please

[Ron Finney]

Unfortunately you probably have too big of carb for your application. A 1050 or maybe even a little smaller carb would be a much better choice. Carbs siphon fuel based on a change in atmospheric pressure. When you snap the throttle quickly, the air rushes in to equalize pressure from the low pressure inside(vacuum). Since fuel is heavier it takes longer to get there. The purpose of the accelerator pump is to mechanically squirt fuel until the siphon feed can get started. Increasing the squirter size may help, also check your pump arms and make sure they don't have excess play or need adjusting. Even with this, you may still need to downsize to increase the draw on the circuits in the carb.

I did the same thing with a 1250 on a big block in super comp. When I snap throttle it would bog or die, but if you could keep it running it would fly. Also, when I would enter the water box and just give it a hit to turn the tires slightly before doing the burnout, it wasn;t punchy. Much better with 1050 back on.

Good Luck.
