I found a mechanic got bike yesterday and it has mo power and the idle screw is not changing when I turn It! It kinda goes good on flat ground but have to pedal uphills! There are no airleaks any ideas? Thanks
If it ran good then suddenly lost power, and the idle screw does nothing, and you have spark I'd guess you have a clogged up main jet.
My bike would barely pull me home, all of a sudden, and that's all it was.
The jets are so small it doesn't take much to block them.
Clean up the carb and that main jet, check fuel flow out of the line before reattaching it, and try it again.
Good luck with it!
It never ran good its new engine! Iam gonna change carb I got spare iam no mechanic I just screw things up but I can change carb! I just know my first bike went about 35 mph this one about 10 whats the point if it only goes 10 mph? Lol
