    I just thought I'd share a shocking[​IMG] discovery with you guys.......

    I've been having some really goofy fuel supply problems with the 84. I checked my fuel pressure- the electric pump is putting out almost 4 PSI, which is lots.

    Well we tore into the carb and discovered that the little spring that connects the float to the needle was never installed when my carb was rebuilt. It hadn't fallen off, IT JUST WASN'T THERE!!!!!. I've had that carb on the truck for four years, too. We figure that the only reason the truck ever ran was because the electric pump had enough output to keep the needle floating, and that after four years of operation the housing my have varnished up just enough to make the needle stick shut after the engine was off for a while.

    Just in case, I threw a couple of bottles of gasline antifreeze in the tank(maybe a watery batch of gas was causing some freeze up at the needle/seat).

    In any case, the truck is now running[​IMG].........I hope this stupid chapter is finally over. Goddamn rebuilders anyway[​IMG]!!!!!!

    Yeah, it's funny- up until now I never really knew that much about carbs. I kinda knew the theory behind how they work, but after hours of chats and research, I am much better aquainted with how the truck gets fuel. Heck, at this rate, I'll be able to give the Grimster advice in a couple more weeks!!!!

    YA.........RIGHT!!!![​IMG] I think Grimmy has forgotten more about carbs than I'll EVER know!!!!!![​IMG]

    Another strong argument to do it yourself...

    Glad to hear it's fixed!
