Mr. TP:
Answers: "Did you purchase the engine/carb new?" Yes, in June 2005.
"Was it set up by someone?" Yes, by the engine builder.
"Do you know if it ever ran correctly?" This particular problem has been here since day 1. I have just been living with it.
"The reason I ask is because it may be something like a worn ACC. Pump or diaphram. If this is a problem that has always existed it could be that your acc nozzle is still incorrectly sized or that your shot needs to be adjusted. How does the motor react when you slowly accelerate from an idle?" Motor does great with slow acceleration from idle. As for accelerator pumps, etc., I have a pink cam (#330 I believe) and have tried it in both the 1 and 3 positions. Position 1 (if I understand this stuff correctly) gives the most volume quickest. I have changed the primary nozzles from .031 to .035 to .037 to .040 with no effect on the hesitation.
Thanks for your continuing interest.
