Status: offline 		I sent my engine in for service just yesterday. The engine is mounted on the side with the throttle arm down. Just started a high frequency fuel drip from the throttle arm. It's a year old with no more then 3 gallons of SIG 15% through it.
Ordered a gasket/o-ring set. Replaced the the throttle barrel o-ring and the needle valve o-ring. Replaced to gaskets; the gasket on the air chamber and the carb manifold gasket to the engine. Still leaks fuel from the throttle arm area.
Gasket & o-ring set are just under $40. Very pricey...
Anyway, I caved early and sent the engine in to service. In case this has happened to anyone else, curious what the 'remedy' might be.

Status: offline 		Chances are the leak is being caused by either a piece of debris under the plunger or a bad plunger. None of the bits you replaced will likely have any effect.
