jet size
John, I have a 565 on alcohol with BLP pump, 1250 Bolaws carb and i run 216 jets and its not too rich. EGT is around 1,040 degrees and plugs look good. I tyr to leave the line at 140 to 160 to run consistant. Hammertime is right alcohol does like heat, if you get it to around 180 it will be faster,but if you run 160 1 time and 180 the next it will run different et.s. I also run 34 degrees timing. What is your fuel pressure at the finish line. Hope this helps! Thanks.Don
