Welcome to the Forum...!!!

Did you take the fuel tank off and dump the old fuel out, before you filled it with good fuel...???

Have you pulled the fuel line off the pump, turn the key ON & see fuel squirt out of the pump...??

You may have some of that dreaded Ethanol varnish in the fuel system since it sat for so long. If you have a weak stream of fuel when you check it, may have to do a full fuel system cleaning. Injectors, pumps, etc... Products like Startron would of helped before it sat.

Appreciate all you guys help. Took the fuel line off to check flow had plenty of flow but gas smelled stagnant so took the tank off emptied it got a new spark plug put in filled the tank with sea foam and fresh gas and it started right up like it was brand new. Sorry it took me so long to get back to you all just got everything finished today. and thank again
