man the c5 is running great on hooch...... ive about got the carb system up and going ......and im hoping to match hooches timing so far im on the aggressive advance curve paul made during the meet ... the carb system seems to be right there .. got it to idle at 900rpm just before sun down ...still a lot to do but its going to the next level now .... this thing is revving sweet and even all the way around ... you here that in the smoothness ... im really sold on the sold on the c5 as the best after market product out there ...sorry its taken so long for me to figure this all out .. its been a battle to get a good carb out of these junk carbs I had to work with and to get them adjustable without destroying the carb body ...always rough when you go in blind and info is not quite right to go on
