Air Fuel Ratio

You want around 11.5:1-12:1 on the spray,then jsut small adjustements from there untill you got the msot mph at the track.

ok so by smal adjustments what exactly will that be?

Main jets,high speed air bleeds,and power valves.They affect most of your WOT A/F ratio.

Dont worry to much about the idel circuit,set the mixture screws and check to make sure there isnt a stumble.If there is,put in larger squirters.

And of course the smallest adjustments will be fuel pressure and float level (oh,and if you dont have jet extensions,you should get some,they keep it from going lean at lauch do to the fuel slaushing back in the bowl at launch).

And with the nitrous on,use the fuel pressure to fine tune it and only change jets if it needs a larger adjustment.
