Hi, After about a year of my '56 GMC model 150 sitting with a damaged exhaust valve on the 270 small port, I have had the valve job done, got it all together, and when I used an electric pump to prime the carb, the fuel just gushed out the little 3/16" angled venturi? tube at the top of the carb throat. 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

Problem solved- the float was a little cocked so the toe-of the-float float level reading was off. No gushing now. Sometimes the time to write a question here gives the mental space to try again. Maybe the too high float contributed to last years monster backfire.

In a different lifetime, when I was a computer systems programmer, and had a code problem that just had me totally stumped; I used to call in someone that knew absolutely nothing about programming, and go through the code explaining the code as I went. Generally, it took about 15 minutes or less to find the gremlin.

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.
