Holley 94 Correct Fuel Level In Bowl
 

Good morning, y'all.

I need your input. I have a freshly rebuilt Holley 94 ECG (rebuilt by seller) and I'm under the impression that my motor is being flooded. My diagnosis may be wrong - it eventually bogs down at idle but will come back to life if I mash the pedal. I checked the fuel bowl soon after it quit on me and I wanted your thoughts on the level of the fuel. I know a bit about Holley 94's, but I'm not well versed. The fuel is at the level of that hole in the pump tube (is that the correct term?) and I was curious if it's supposed to be that high. I THOUGHT fuel should only be going through the two orifices on the bottom of the bowl.

Well, you got me on that one. It’s never occurred to me to examine the actual level in the bowl. The measurement is taken at the float while the air horn is detached and upside down. Rebuild kits usually come with a rinky dink cardboard gauge for that purpose. Upside down will be in a closed position for the float valve, replacement valves may position the float differently than that float being replaced. The measurement is taken from the gasket surface to the top center of the float, taking care that the float position is not cocked higher on one side. Long ago, I created a measuring gauge out of a beer can, so now I can’t recall the exact measurement, I think maybe about 1 5/16”? Not sure of that.

i suppose one could remove the top of the floatbowl and the float and use a turkey baster or syringe to fill the bowl with gasoline (very dangerous BTW) while the engines running and see how it affects the performance.

not something i would necessarily recommend but might prove edifying. :)

That works with 97's, but not 94's for obvious reasons.

I have taken to lowering the float level between 1/8 and 1/4 from factory directions. The alcohol gas and hot temperatures in Texas will cause the gas to boil over down the carburetor when the engine heat soaks. If I take the float too low the car runs out of gas at high speed, and I raise it up a little.
I am used to the fuel level being a bit lower than that hole in the accelerator pump well. There is no point to having gas on top of the accelerator pump.

looks like a fuel saturation level just under the red line where its been for quite some time. Tom.

Is that about where it should be?
