Cars that sit awhile.
I'm rebuilding the Holley.
It has been awhile since I've torn one all the way down. A few days ago I started this thread:
Can a stock fuel pump produce too much pressure?
I had two carburetors in a row that flooded over when the engine was running so I suspected the fuel pumps were making too much pressure.
I swapped in a good carburetor from another car and it ran great. The problem was in two carburetors in a row. It is strange when the symptoms mislead you.
I did pull this carburetor....
...I took the bowls off to clean them out. The needles and seats were replaced along with the power valve. Once back together, it didn't flood over but it wouldn't idle. I had to hold the throttle 1/3 open to keep it running. I don't know what I could have done wrong. It didn't appear to have any external vacuum leaks. I tested it again today and it ran the same as before...no flooding but no idle. Now it is soaking in Berryman Chem Dip.
These aluminum Holleys sure weigh less than the old style die cast greenish colored carburetors.
