I just got a 82 fl250 and I'm trying to get it going. It pretty much came with double everything. I got it running today and it will idle but when you give it gas it boggs out and blows back out the carb. I have tries everything cleaned and replaced the carb, changes cdi, coil, and plug, took off the exhaust pipe, sprayed break clean on all hoses, and around all seals and gaskets, took the gas cap off and replaced the full pump and its still doing it. What am I missing?
