I AM SWITHCING TO ALKY THIS YEAR AND I AM LOOKING FOR SOME BASE LINE JET SIZES AND SOME INFO ON DIAGNOSING MY MOTOR TO TELL IF IT IS TOO LEAN OR TO RICH
I BOUGHT A DEMON 775 FROM SOMEONE ON LINE AND IT SOUNDED LIKE HE WAS RUNNING A MOTOR IDENTICAL TO MINE BUT THIS CARB HAS 177 AND 172 JETS IN IT SOUNDS TOO BIG AFTER READING THINGS ON HERE
MY MOTOR IS A 355 WITH DART SPORTSMAN HEADS
RUNNING AROUND 12 TO 1
ANY INFO WOULD BE APPRECIATED

That sounds correct I think on the demon they run the bigger jets the others drill a .100 hole near the jet to allow the extra fuel in

We run a Braswell 750 on a pretty basic 383 with all four corners in the 140 range. The right side secondaries and primaries are about two steps lower than the left sides. That means if we have a 144 on the left secondary corner, we run a 142 on the right secondary corner. Same for the primaries, although usually larger (I think) than the secondaries. The reason for jet stagger is because of centrifical force in the corners and straightaways.

I am not a guru on this subject , but have leaned a few out in my day. I ended up going with a carb company that held my hand through the learning curve. In hind site, jet it fat and go from there , a size at a time.
