throttle not closing all the way

thanks for all the input guys

this is where im at

i felt like the throttle cable was not pulling smoothly through the outer sheath so i replaced the inner cable with a new one (covered in graphite powder of course)
i checked the air cleaner clearance, plenty of room there
checked the throttle blades, they were in place and snug (also, no sign of binding down the throats)

the engine was build by MRL so i am sure the throttle arm bracket is correct

the kickdown is a lokar cable, so no binding there

i put a little bit more tension on the return springs, but they looked good, to be honest


i took her out for a test drive but the second or third time i got on it, the throttle cable end popped off, so no more updates untill i buy a new one of those
