Time to dig in to your fuel system, and make sure your gas tank is clean, fuel line is in good shape, fuel filter (if installed) is in good shape, carb is spotless inside (this is where I'll guess you'll find a very small bit of something clogging up a needle or passage in the carb). Some carb cleaner and a pair of safety glasses are in your future. It doesn't take much on these small engines to mess things up. We're not talking a 454 cu.in big block with a 750 CFM Holley resting on top of it, after all..:wink::laughing:
