4160 holley

[slapstickjim]

Looking for your thoughts.

I bought a dart sport in January and been addressing a small list of things to tweek. The holley 4160 sits on top a mild rebuilt 318 and runs great. I honestly have not seen or worked on a carb in forever, so I'm rusty.

Over the weekend I had the dart out a few times and was smelling gas in garage after I parked it. Then on. Monday I went to back it out and it had trouble running and starting. My thought was seems like it's flooding. I took aircleaner off and with it running,, gas was dripping in secondaries. More like a super strong drip almost a stream. When I shut engine off it kept dripping and started running out of carb at butterfly thingies. Read up and suggested bad or dirty needle or float to high.

Being I have not touched a carb in 25 years, I'll give run down what I tried. I took the screw and 5/8 nut off attempting to remove needle and seat. That did not remove needle. So With nut and screw off I blew in there thinking to release dirt. Reassembled started car and adjusted rear float, so gas came out when I would rock car a lil. While at it I adjusted front float also. And took for ride and back home that gas drip cleared up. So far cost me nuthing.to do this.

Questions.
1. Was that the problem?
2. Did my fix fix it or should I removed rear bowl to get dirt cleaned up?

2 other things with carb questions but this issue first

Thanks for your input

Probably was the problem.
When I don't use the car for several months (general winter) I always check the Holley for leaks of sticky inlet valve and flooding.
The hot days we had are another thing to watch out for. The expansion of the winter fuel and even a bit of vapor lock are an issue when its 80 F and we're still on winter fuel. Even my '85 Jeep had a bit of vapor lock leaving the gas station last Wed midday.

In the future it might be wise to rebuild/clean carb and fresh fuel filter.

Sticky floats are common on a parked holley.. On holleys, I change the accelerator pump every few years to avoid that leak.
I love holleys, and have learned to work around "holley disease".
Carb maintainence is like changing oil. Do it enough and its simple.

So your saying not uncommon for floats to stick? But taking bowl off and clean is not urgent but wouldn't hurt?

Fuel blended for easier starting in cold weather.
More tolulene or benzene, I forget but not to hard to look up. Cheaper ingrediants too.
