What size jetting do you run in your 1050 alky carbs. Our lm1 o2 unit says we're rich at 152s. I don't beleive the unit. We were running 188s until we installed the o2 unit.ET hasn't changed. What are your opinions?

imho it depends on the carb builder what jets it needs do to the way he design the other circuits. i am running 128. makes good heat and burns 1 gal on an 1/8 pass, 5 qts or so on an 1/4 pass

It's an APD and with all our dragster info they sent 188s and 192s with it. They are holley alky jets.

carb builder is critical to jetting. my Apd uses 186-194 and my rupert uses 164. If there was no gain in et or mph I would jet back down.
