If the poppet valve is in the full open position when the throttle is in the stop position you have a major problem,something in the carby would have to be broken,missing ,backwards or installed
incorrectly,near the stop position is the choke position so the poppet valve will be open more than
the idle position.One thing to look out for is where you locate the outer throttle cable in the plastic body,there are two positions the cable can be installed, if it is in the wrong one you may not get full throttle or it may not get to the stop position completely and there is a cable adjuster
at the other end of cable so I always check the cable is working correctly and adjust it if needed.





When the 3 leg plastic part is on the ramp that is when the cable will decrease RPM or Increase RPM ,depending which way you move the cable.

If your RPM is to high ,once I had a poppet valve that was longer than it should be so I replaced it and some of the 3 leg plasic parts
have a sholder that sticks out stoping the poppet valve opening to much.
