Starting I don't get it.

[mrbobs48]

I have a rebuilt fuel pump, good vac. Rebuilt carb no leaks. I choke the car it starts cold. Run for a couple of minutes or longer. Turn off the car let sit for a minute. Won't start again, yes I have the shield for the fuel pump. I wrapped the gas line with header wrap. I push the throttle look in the carb dry no gas. I adjusted the float 5/64 3/64 and lower. still the same thing. I drop a little bit of gas in carb, boom starts right up. What am I missing.

Try a little gas pedal while cranking. The manuals recommend 1/3 to 1/2 open.

Also before you try to start inthat situation, remove the air cleaner and manually open the throttle to full open while looking down the carb. YOu should get a nice health squirt of gas from the accelerator pump. If not then remove the top of the carb and see if there is gas in the float bowl. If its dry after a short run you likely have some supply problems. related to flow from the tank to the carb.

Since you are now getting into colder weather check to see if the base of the carb where is botls to the manifold is not icing up. When weather starts to get colder and the gas vaporizes and the heat riser is not working the base of the carb ices up and the car will stall out.

Yes there will be a white film of ice like frost onthe base. This might be your issue. Pull the choke cable out to keep the idel higher and check the heat riser and wire is open to get heat upto the base of the carb.

This is a thought on your issue.

I took off the air horn there is gas in the bowl, also did the 1/3 gas pedal too. Still not getting gas in the carb. What else could it be. Once it starts it runs good , just want drop gas back in the carb to start again

Bob,

A quick and easy help if there is possible blockage in the fuel line somewhere is to pull the fuel line from the inlet side of the fuel pump and blow low pressure air back through the line into the tank. If you remove the gas cap before doing so you should be able to hear it bubbling in the tank. If the in-tank filter gets clogged with silt this will clear it for a while. Install a cheap inline filter before the pump and keep an eye on it, it will catch the dislodged silt before it gets to the pump.

Had a problem something like yours and finally dropped the tank and cleaned it out good. Went through the above procedure 8 or 9 times and changed the inline filter about 4 times over a several month period until all the silt was cleared out.

You say there is gas in the bowl but not in the carb??? don;t understand that statement. When you removed the top of the carburetor, there was fuel surrounding the float? If so then no gat to the carb doesn't compute.

Next question. where is your timing set??

[mrbobs48]

Yes there is gas under the float in the bowl . No gas dropping into the chamber throat of the carb. While playing with the float in gas with the horn off. I push the throttle and look in the carb, no gas going into it the throat of carb. Gas in bowl just no gas squirting in carb. It squirtsin the carb when running but not running. Does that make sense.

Sounds to me like his accelerator pump is not squirting gas in the carb on startup. Did you loose the little ball at the bottom of the accelerator pump ? If so it'll never squirt gas and there will be a flat spot while driving and trying to accelerate.

[greg g]

probably the leather cup at the bottom of the plunger is shot. Once it looses contact with the walls of the chamber it stop pumping. The plunger assembly center bottom of the pic is sometimes avaialbe from NAPA. If not George Asche has them his number is in the parts vendor list.

The check balls ar visible i the gasket tot he right. If they ar missing or gunked up and not free to move the acc pump won't.

I GOT IT. I want to shout. The plunger paper end was off the plunger just like the one in the last picture that was posted. Squirting gas good now. IM HAPPY> Thanks everyone

Hi Bob,Glad you found the problem.I was wondering what you referring to as the paper end on the plunger?

[greg g]

You still might want to source a new one. Once they start to give up, the deterioration process doesn;t take long especially with the current ethanol mix. The material is leather, if its starting to look like paper you got trouble.

Glad you found the problem. Just don't get to happy pumping the gas on hot starts or you can flood it.
