what carb?
38 VM?
this is on a 88"
vm38, I have a 35 idle and a 330 main, all the other parts are stock, as in what came with the carb.
I also run the needle at the highest clip setting, (the C-clip is in the groove at the top).this will make it run rich or lean at 1/8 to 1/3 throttle, I moved it 2 slots and it ran rich so it went back to what I have run for years, this will fine tune it
I also drilled out the fixed choke jet from .025 to .038, as it was not getting fuel that it needed to start a cold 88", there is a small air port in the bowl that I think I will plug to see if it will draw more fuel on choke, kinda like a miki 42 flat slide, these just draw straight up from the fuel bowl with no air vent, and it starts a 95" up real nice all the way into the teens
on my 74" I had a 25 idle and a 280 main, needle is the same as above.
the choke supply worked like it came set up with. .025 jet
also make sure you have no intake leaks.......
