ugh...man im new to banshees and all but not to motors. But i dont know if u got fire out of both wires then any amount of fuel gettin in there should fire. Might run like shit but it would fire. The reed would be the quickest thing or you could have a blown head gasket on the right side...thats all i can really think of if your gettin good fire outta the plugs. Do a compression check and see if it the head gasket and then check the reeds.
