Check Your Reproduction Throttle Cable Twice

I'd be looking for another supplier. The hole at the carb end shouldn't be a problem though. There won't any noticeable slop in the connection assuming you have the correct pin on the carb, a proper return spring, and the correct adjustment on the cable. The other end is a different story. You now need to find a better fitting E-clip and hope there's no water leak between the cable housing and the rubber grommet.
