Partially open throttle - is this normal?

[SuedePflow]

I connected my throttle cable to the carb last night and the "barrel" in the carb does not fully seat when off the throttle. Is is supposed to be slightly open like this when off the throttle?

I think so. thats how mine is. and it runs great!

it sits on the idle screw - turn the screw and see if it moves up & down, if not, then your throttle cable is adjusted too tight or your throttle grip may need trimming for more slack

I'll check the idle screw when I get home tonight.

So just to confirm, it is supposed to be closed?

No I don't think so. mine is exactly like the picture you put up.

Thanks. I also confirmed on another forum that they way it is in my image is the way it's suppsoed to be.

no, it is supposed to be controlled by the idle screw - turn the screw in & it opens more - out & it closes more

if it doesn't move when you turn the screw, then it is stuck or the cable is too short

it isn't important how open it is, just whether the screw can control it both ways

Found out the hard way. I just fired it up for the first time this afternoon and it drove off uncontrolably. lol

It seems my cable is bit too short. I had to take off the threaded adjuster at the top of the carb and drill it deeper so that the cable sat in deeper. Problem solved.

one can also use a razor blade to trim 1/8inch off the throttle grip where the cable hooks in
