Fuel Fluke

Well guys it was the frickn' carb!!!!!!!!!!!!

I took the 750 Holley off and installed my old 500cfm Eddy carb. Drove the exact same route and when I got to where it always started acting funny the car just kept going! I drove around for awhile and even put some gas in it for tomorrows cruise in. Yipppeee!

The Eddy does not have the "punch" like the Holley does.... I find it very difficult to even bark second gear and the acceleration is lousy (I mean its only 500 cfm). So what do I look for on the Holley that is causing the stumbling? I took the front bowl off and looked in it awhile back trying to diagnose the problem. It did not have a spec of contamination in the bowl or float needle. Bad power valve?

I couldn't check how much fuel pressure I have now because the psi gauge is mounted on the Holley's fuel block. But whatever pressure I have the Eddy is taking it without trouble.... the Holley must need to have less or more pressure but I don't know which. So that's another factor I'm considering is there isn't anything wrong with the carb just not enough or to much pressure. With the stock pump I was showing a steady 7.5 psi the day I installed it and after I test drove it idleing in the driveway.

The Holley is a low miles deal.... I have not even had the carb a year yet!

Let me know thanks!
