i am wondering if i can drill my power valve blank in the pic above and put a jet in it or screw in adjuster to fattinup the intermediat. or all and i can use [Edited by Moparts - Family Friendly Site - Keep it clean] bleeds in the hs then.

Thank you 3404 and i agree i dont want to endup with junk
carbs!
the jets in the plate are 110. the high speed does ok at 12.8 a/f but needs more with those jets.

I cant believe you need 110 jets on a PAIR of carbs
unless your running E-85 and then it still doesnt sound
right

i know mr p.some info on the carbs,it came with 100 jet and power valves so i blocked them and jettup.it is a 1250cfm carb. like i said the high speed is close at 12.8 a/f and i have not touched those bleeds.just the intermediat is lean.

i still have 2 1250's on it so i believe the lean condition because i an only using the pri side of the carbs reving it and load testing in gear.i have no down track data other than in the traps at 12.8 a/f.

i am realy thinking about drilling powervalve blanks/plugs as an inrichment meter.i can start with the pri side starting small.030 and go up.the plugs are cheap.[3$]

update:i talked to APD and i need to drill the hole next to the main jet in this pic and i will be able to come down in the airbleed eventualy so now the pv drill is no longer an option.
