I have a 1990 four Winns freedom with a 4.3 V6 cobra engine with a Holly 2 barrel carb. When I give it full throttle, the engine hesitates for about 2-3 seconds then accelerates. I set the points gap at .019" and the timing at 2 degrees. If the engine is a high output 4.3, the timing should be at 6 degrees. I don't know if the engine is a high output or not, with a 2 barrel I figured it was a low output engine. <br /><br />After the engine was warm, I had someone else operate the throttle. I held the choke shut, the motor did not hesitate! Is there an adjustment for the amount of gas that the carb. shoots from the upper jets down on to the butterfly. On the arm that operates the accelerator pump there is a bolt with a spring. If I adjust the height of this bolt, will the amount of gas change??
