The elec pump (which I have used before with no problem) puts out a little less than 2 psi. Too much? I adjusted the float level to no avail, now I am wondering what my next step is. The carb was rebuilt last June, and it ran for two weeks before I blew up the muffler. (you may remember that) The float works if I hold it up with the cover off. I have the carb on a tray with a long fuel line so no more gas in the engine.
Well, my time went so quickly,
I went lickety-splitly
Out to my ol' 55.
As I pulled away slowly,
Feelin' so holy,
God knows, I was feelin' alive..... Tom Waits, Ol' 55
