So ypu had it on the bottle huh ?

Gas is dry , over a period of time it dries out the accelerator pump gromet that seals the chamber and pumps the fuel out through the accelerator pump squirters. What your getting now is when you mash the go peddle the throttle is opening and the enrichment fuel that the pump shot is meant to supply is not there. all you get is a pop a croak and deadsville, which is about 2 feet from where you mashed the throttle.

To fix replace the pump seals.
