Before you start replacing things, do the following:

(Make sure your timing and advance is spot on first, before any changes.)

1. Adjust both float levels to the base of the sight plug (assuming you have a Holley). Test drive.

2. Make sure accellerator pump is squirting immediately when the throttle is moved. Test again.

3. Try opening the idle air screws an additional 1/4 turn (richening) from their current position. Test drive.
