I have a 33 Plymoutth coupe it has a 48 dodge 230 6cyl in it. I'm running a triple carb manifold with 3 carter weber [motorcraft] carbs. I built the motor about 3 years ago but I had some personal problems + Ijust recently installed the motor in the car. The carbs were new but they sat in my hot garage [south Florida]. The carbs keep flooding out, not any particular 1 they take turns. I reset the floats a number of times + it will run really good for awhile. When I shut it off + restart it it will start flooding out again. Is it possible that the float needles were damaged from sitting so long or is ethanol in the gas causing damage to the float needles? The float needles have rubber tips. I'm getting really pissed, I couldn't drive my car to billet proof I had to go in my suburban. Any body go any ideas? Thanks Lanny
Perhaps the fuel pressure is too much for these carburetors. Are you using the original mechanical pump or are you using an electric pump. If you are using an electric pump, you should use a fuel pressure regulator and fuel pressure gauge to determine a safe fuel pressure to use. Sounds to me like you have too much pressure in the fuel lines and you are by-p***ing the needle and seat. Did these carbs set for 3 years with fuel in them? Perhaps you'll need to tear them down and clean them up.
Do the needle valves have neoprene tips or are they solid metal? If the tips are neoprene they may have dried out and are leaking past. Are the floats br*** or phenolic plastic? Are the carbs set up in tandem or progressive? Flatman
ONE CRUSTY ONE the carbs didn't have gas in them + Ihad them apart they're like new I have an electric pump with a regullator I tried defferent pressure settings didn't make any difference
Do the needle valve tips look smooth, no ring marked around them from the seats? Are they still soft? Are you confident in the reading from your fuel pressure gauge? Flatman
If the tips and floats are good and set right, you'll have to look upstream for your problem. Sticking regulator, bad gauge... Are you running a return line from the regulator to the tank? Flatman
Is your fuel pump a high volume pump or a regular pulse pump? What make? A high volume pump would require a return line to the tank. Flatman
I went + bought a new fuel guage + set the regulator for 3 psi IT"S ALIVE I can't believe how good it runs. It had me seriously thinking of the s**** yard but cars are like women sooner or later they finally straighten out. thanks for all you guys help
Re; Fuel pressures,...If anyone is running the new Stromberg 97, be sure to stay with 3 PSI,...These repops are exactly like the originals, in that respect !!!! 4TTRUK
Finally straighten out ..... really? Seem that car got you to do exactly what It wanted. still alot like women though. Haha glad you got figured out.
