Flooding Problem 1954 Dodge
-
Well, this is more of a plea for help from Oldcar Mechanic.
I have the old 6 cylinder in this car that I'v been restoring at work. I've been driving it in & out of the shop over the last few months that it was there, until I got it towed home. Took it off the flat-deck and thought it rather odd that it was hard to get it started to drive it into the garage. It did start, but ran realy rough and as I backed into the garage, it stalled. After several attempts to start it back up again, it felt as if the choke was full on. The carb had not been rebuilt at this point so I decided to buy a rebuild kit for it and rebuild it. Alas, that did not cure the problem and it continues to flood profusely. I'm a Painter by profession, working in a body shop, Although I do have a fair mechanical aptitude. However I have run out of ideas and am at my whits end, I even put the car on 'craigslist' but I know I'll never let it go!!(http://vancouver.en.craigslist.ca/cto/858540124.html) (If you're curious to see it) Any way, I would be greatfull for any help, Or if anyone has also come across this problem befor Thanx for reading, Phil. -
As you say a "flooding profusely" carb only has a few reasons.
1) To high a float level
2) A float that is absorbing fuel and sinking
A styrofoam type float can absorb fuel.
A Brass float can have a pin hole in it or a solder joint gone bad
3) A faulty needle and/or seat (not sealing the fuel off when needing to)
This could also be just dirt lodged in the seat.
4) To high a fuel pressure
I am assuming that the fuel is pouring down the throat of the carb or out the air vents on top and not just dripping through the main circuit.
I have seen this very thing happen many times after changing a fuel filter. A small bit of dirt becomes lodged in the needle and seat and the carb floods. One way to try to clean this up is to pinch off the rubber fuel line just ahead of the carb (as long as there is a rubber fuel line) and run the car until the car stalls due to lack of fuel. Remove the clamp and try to start the car. Many times this surge of fuel will dislodge the dirt and the car will run fine. Sometimes I have had to do this a couple of times.
I hope some of this helps.

Thank you, I'm going to try that tomorow.
