carb was rebuilt recently but still has some quirks, im not good with them so i bought a 770 street avenger, i had to rob a fuel line fitting for my street avenger off of it because the one fromt he avenger wasnt threaded ( quality control??) i will put the un threaded unit on the carb so it will have to be threaded before you hook it up of course. its a model 3310-4 which is a 4150 i believe. asking $50 for it plus shipping email me at knockyerblockoff@sbcglobal.net
