any body CAN HELP PLS...

 

U usually have to adjust the idle after putting 4 ks in. There is an adjuster on back of pump. It has a lock but on the bottom side.
The hanging rpms coul be several things. When removing the shins, are you sure u got them all out? If not that will cause some problems. Is the throttle cable hanging?

 

no it gos back like it should but even if i dnt hit the gas it still goes up an up an want come down im goin recheck every thing an spray it all down with some lube an c what happens
