Take the dash pot cover off then see if piston moves up and down freely, if it does not the jet bridge may be bent, if it does put the cover back on without screws and check again, if it moves without the screws replace the screws, if this stops the piston from moving, you know where the problem is

I came across a problem once where too large a screw driver was used to tighten the bell to the carb. This caused the bell to be dented next to the bolt. That closed the gap between the bell and the slide causing it to stick.

thanks a lot fellas i appreciate your help it would only stop when you screw down the dashpotso i lifted the piston screwed down the dashpot and then let it go and it fixed the problem. thanks alot fellas or all ya help yous are champions!!!!!
