Gilera runner 172 28mm carb help

ive just finished putting my engine back in my bike with brand new 172 kit , when i started it and ran it for a couple of minits it idle quite high, what could be the porblem , im guessing i need to raise the clip a knotch because when i fiddle around with the idle mix it did not do anything , unless ive got a hole in the rubber manifold which could be the problem 2 couldnt it . ps the carb is 28mm. cheers.

 

maybe try idle speed ??

are you sure your qualified to have a highly tuned motor ? :rofl:

 

and are u quilifed to read imp: , i said i played with the idle screw and said it did not make no diffrence . and yes i no im an idiot i did not check the manifold for cracks . and what is a good notch to start with on the needle .

 

you sad idle mix not idle speed :bird:


middle notch is a good place to start i would have though

but doubt the needle postition would make it idle very high

 

ite cheers mate .
