I have a Hummel 45 hp 1/2 VW engine with a Zenith 14992 carburetor. I attempted to adjust the carburetor per the Hummel manual to no avail. The engine stutters with the advance of the throttle. Also, and most concerning, the engine kills when running at 2300 RPM or full throttle. Per Scott Casler at Hummel, it's not getting fuel… however, fuel pressure gauge is showing 3 PSI plus. Any experience with tuning a Zenith carburator would be appreciated period.

Thanks for your response, Dee
