I'm very hesitant to get into any discussion about carburetor problems especially with regard to Holleys. I've had so many problems with them over the years. Don't want to go there but here's what I found a couple of years ago with a Holley 2V - the middle one on my tri power. It was doing what your's is doing now but of course there's only a primary side. These Holleys were completely rubuilt/refurbished to just like new condition by a man named Joe Bunetic in Ohio. He does beautiful work. I'd run this set up for few months without any problems. But one day after firing the "390" up I smelled fuel. I popped the hood to have a look and "Oh S#5@" fuel leaking all over my spotless intake manifold. This same thing has happened numerous times to me with other Holleys especially after the vehicle has sat for awhile. I'd learned to initially blame the most common culprit(s).....those cheap rebuild needle & seats. So with the tri power, I did check the float level first.....whoa.....the bowl was totally filled! Yuk, more mess. Out comes the N & S. They look good. I lube 'em up. Back in and that seems to take care of it until the next short idle(car sitting) period. Again, gas spewing out. Must be the fuel pressure is too high due to that Mallory electric fuel pump. Fuel Pump maintenance. It was fine. Fuel Pressure was right at 6.5-7 lbs. New needle & seat. Good until next time again. Hmmm. What about the float?
That's what it was for me. It was an original float that looked excellent. But it was full of gas. Too much weight for the needle valve to keep afloat. Apparently, once under power and after a drain down of that bowl, the needle could keep the float up but once the car was shut down for a short time.....big mess.
Long story but that's how carb stories so often are. That's what took care of it for me....a "brand new" used float from a spare Holley 2 barrel did the trick. |
