Carburetor Adjustment
Posted: Thu May 16, 2013 7:26 am
I need some help with the zenith carburetor adjustments.
When I got the tractor it would miss at an idle, but run great in the midrange & at wide open throttle. I turned in the air adjustment (top of the carb) in to richen it up. That solved the miss at an idle, but now the midrange is not well. It cuts out while accelerating to full throttle. If I turn it back out 1/4 turn, then it goes back to missing at an idle, but the midrange is ok again.
I can't seem to find a place where both run well. Is there a better way to adjust the carb than by tweaking and running it?
