ok i have a os ax 55 on my decathalon and i can keep it running on the ground but when i get in the air and fly for about a min or two it acts like it loses fuel and just dies... i have a pits muffler on it had to jb weld on of the pipes back on it it had bent and went to bend it back and it broke well the jb weld didnt hold and one of the pipes fell off of the muffler... do yall think that this might be causeing the muffler not to hold enought back pressure on the tank and making it lose fuel
