Re: gas lines mixed up on 18.

not quite sure what you're asking, there is no return, there is a pressure line from the crank,thats if you are still using the old pressure tank. if you are using the original pressure tank, look where the lines connect to it, one says "fuel", the other "air". follow the fuel line up to the connector, then from the connector to carb. (if your tank wont hold pressure, your motor might start, but it wont run, make sure the cap is on tight, and loosen it off when not in use)

i have the fuel line going to the filter then to the carb the air line goes from the tank to the intake manifiold is this correct. it seems to have gas in the bowl but not getting into the venturi it has a good spark fired with either sorry wont fire by itself help dave

Re: gas lines mixed up on 18.

just responded to the other thread! i think i have some of this info figured out.....your lines are on correctly. you installed an in-line filter (is the direction of flow correct on the filter?). have you tried squirting some pre-mixed fuel into the carb or plug holes, to see if the motor actually will attempt to start? it does sound like you need a carb rebuild.
