pz19 carburetor adjustment for idle bog and clean throttle response
I am trying a pz19 carburetor adjustment on a small engine that starts, idles poorly and bogs when the throttle opens. I want a baseline before turning every screw.
I found this related page while comparing notes: pz19 carburetor adjustment. I wanted a practical thread before guessing.
Would you clean the pilot jet, check main jet, float height, needle clip, air screw turns, choke seal, manifold leaks, fuel filter, bowl gasket, plug color and cable free play first?
