what he said. sounds like a bad gas problem to me. may need to pull the carb and give it a good cleaning along with a fresh plug.

tryd new gas new plug cleaned the carb countles of times i dont know what else to do could it possibly be the oil injection oil being old from sittning all winter i never put fresh injection oil didnt think that would make a difference?

could be a gummed up oil pump or hose as well. its very possible thats helping the problem. it doesnt sound like a reed or compression problem. its gotta be somewhere in the fuel/spark part.

i had a similar problem. it would start and as soon as i would gas it, it would die. i took the reed cage out and one of my reeds was cracked. as soon as i replaced it, the engine ran like a champ

yeah wish that was just it but my reeds are fine

what about the fuel petcock? maybe its gummed up and not allowing enough fuel to flow? gas is a nasty thing when you let it sit around for a while and causes all kinds of problems.

the gas flows through the petcock but i did forget to mention that when i unscrew the bowl screw to drain the gas it doesnt really drain much and doesnt drain smoothly but the float seems to be fine i dont get it ive thoroughly cleaned every hole in the carb so many times already

that doesnt mean you got into the small cervices inside of the carb. you would be suprised at how little it takes to block your fuel flow. dunk your carb in isopropyl alcohol and let it sit in it for a couple of hours completely submerged. take it apart the bvest you can before doing this. once it has soaked let it dry for 24 hours and re assemble. that should help break up the varnish that has gotten in the small holes.
