Q: I'm having an issue when I revved the motor up and let it come back to an idle, it stays at a slightly higher RPM and then slowly settles into a slower Idle , Could you please give me a recommendation to cure this problem please?
A: The problem could the return springs on the accelerator pump diaphragm. Look at the exploded view on your instruction sheet. There are 2 small springs on top of the accelerator pump and 1 big one that goes over the pump at the bottom. Be sure all of the springs are in place.
The biggest spring is the return spring which will return the throttle. You can try stretching the spring a bit and see if that helps.
The last thing to do is to put a spring on your throttle linkage to help pull it back.
