pz27 carburetor adjustment after cleaning jets and setting float height
I am doing pz27 carburetor adjustment after cleaning the carb. It starts now, but idle hangs a little and the first throttle opening is not smooth. Tiny screw, big attitude.
I found this related page while comparing notes: pz27 carburetor adjustment. I wanted a practical thread before ordering parts.
Would you set float height, clean pilot jet, check intake leaks, start fuel screw baseline, warm the engine fully, set idle speed, read plug color and test one change at a time?
