i have a holley 750 dp. i havent had much expierence with carbs and i was wondering if anyone had a pic where they could show me the mixture screws. and i have noticed when i step on the gas its hesitates just slightly then revs up nicely. i was wondering what could be done about this hesitation is it a tuning problem or what do i need to do.

thanks ryan

 

There is a wealth of information here http://www.holley.com/HiOctn/TechSer...o/FMCTech.html

Check out the the "Idle System" and "Power Enrichment System" links. The first one answers your question, the 2nd one more than likely addresses your problem.

Note the mixture screws only affect the idle mixture. Once off idle, the mixture is controlled by the main jets (see "Main Metering System") and power valve.
