You might detect the ovaling by looking into the carb, but it is hard to detect as it doesen't take much. The throttle response issue is really evident at high altitudes, might not be so noticable at lower elevations
I have throttle response issues with my TDM. I guess it makes sense since you said it is more evident at high altitudes. Flagstaff, Arizona is at 7,000 feet. Tom S what altitude are you at?
BTW, the red ones sure look pretty!
