David, Right, my flat-tops don't have the smaller-diameter cylinder on top of the piston. What does that do, anyway? Are our carbs the same except ...

@wobbly Thanks for responding! I will replace the ignition advance return springs and lubricate that mechanism. I will also try a higher octane fro...
