yanked out the carb, installed main jet, needle, etc , slapped carb back in...connected all hoses, etc...started it...IDLE IS TOO HIGH!! tried toning it down with the idle control..but it won't calm down...could it be the main jet?

 

it has NOTHING to do with the main jet. You need to learn what each part does.

Its most likely your fuel screw at the bottom of the bowl on the carb. you need to drill out the brass plug first, then turn that screw out like half a turn each time then see if it gets any better. Im pretty sure the stock setting is like 1.5 turns out, so make it 2 turns out and it should calm down. If this does nothing then keep turning it out half turn each time(don't go past 4 turns out though, screw might fall out) also you might of messed something up when putting the carb back on, throttle stickin or the floats arent workin right.....shouldnt be hard to figure out.

btw will it start fine? just idles too high?

 

I did remove the brass plug with the screw provided, when I get home I'm going to adjust that fuel mixture screw to see the difference. Nah I didn't even touch the floaters, yeah it starts fine, takes a little longer than before probably because of the opening that is exposed when idisconnected the airbox and the pipe...but it starts fine, yeah idle is just the problem....way too high but ill adjust the fuel mixture screw when I get home.....
