wont start04

i had the same prob as you but i could only run it slow because it was still gettin very lil gas when i tryed to open it up she would just cut off till i got some more fuel in the bowl which would take like 5 minutes, glad you found the prob
 
yes ethanol eats rubber rite awauy, your supposed to use synthetic things, like silicone, so if you kan find what you need in silicone or synthetic, get it kause you'll only have this problem again
 
yeah when i buy the new one i will go gett a diff o ring. but the lave inside is rubber no way around that!
