There may also be a spring and a Moraine brass filter in there as well. If they are, note the direction that it all goes in (or Google it), so that you put them back in correctly after cleaning them. I know they're in mine, so they might be in yours as well.

This is what they look like. And they're actually a little trickier to get seated properly than you might think. Some Holley's have a teeny weeny little lip over on the inside of where the gasket seats and if you don't get down there and look the gasket sits on top of it funny and you get a drip.

The needle and seat stuck on my Cobra right after our Austin get-together last weekend. Pulled it out and cleaned it off and it's fine now.

How did you realize your N&S were stuck? Was the car stumbling really bad? Smell of gas? Was it pouring through the boosters into the chambers? |
Don't muscle it, just crank it down firm, and a little more, but nothing spectacular. Remember, it's just holding in 6 psi of pressure. On the other hand, you don't want it dripping.%/

Interesting to see this, just redid mine a month ago was starting to get flat on accel and just did not run good . original from 2007 she served the car well . :)

"then it means either your needle and seat is leaking or your floats are too high or the gas you are using is really $hitty and is percolating up and out through the boosters"
...or the O-ring on the N&S assembly may be leaking? I experienced exactly what you described in your write-up but in my case, it was on a cold start (car hadn't been run in days), which takes the percolating gas factor out of the equation. |

Carrying that thought a little further. When I placed the old N&S back into the fuel bowl, it just dropped right in up to the threaded portion with no resistance from the O-ring. Based on the recommendation of using a lubricant around the O-ring, I would think that the N&S assembly shouldn't just 'fall in' to the hole but rather needs to be pushed in due to the resistance from the O-ring. Shouldn't that be the case? If my old N&S just drops in, does that indicate a bad O-ring?
|
Nevermind. I just realized that the O-ring doesn't start seating until you've tightened the N&S a few turns.

The o-ring needs to be the correct size, and lubed on assembly. It is the first resistive part on assembly. A bad o-ring can be a reason for a creeping float level, and flooding condition. |

Glad you have sorted your flooding condition. Gary |
There are no gaskets used with AN type hoses and fittings unless the conical end of the fitting is damaged, then there is a soft washer type piece that can be used to help seal the fitting.
