53 Pilot Posted November 19, 2019 Report Share Posted November 19, 2019 Truck was running fine but now will start then quit when accelerator pedal is pushed. Looking for ideas to correct this issue. Thinking the carb should be rebuilt. Quote Link to comment Share on other sites More sharing options...
dogedood Posted November 19, 2019 Report Share Posted November 19, 2019 Might be bad vacume. What happens when you push down slowly? Quote Link to comment Share on other sites More sharing options...
53 Pilot Posted November 20, 2019 Author Report Share Posted November 20, 2019 Slow or fast the engine quits. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted November 20, 2019 Report Share Posted November 20, 2019 look to see if the wire to the points could be shorting out when the point plate moves... Quote Link to comment Share on other sites More sharing options...
John Rogers Posted November 24, 2019 Report Share Posted November 24, 2019 (edited) Maybe the accelerator pump isnt working. With the engine off and the air cleaner removed, have you checked to see if there is any fuel spraying into the throat of the carb when you manually work the throttle from the closed position? If its not working , perhaps the acc. pump linkage has come undone or something has become plugged up in the circuit. Just a thought.

greg g Posted November 24, 2019 Report Share Posted November 24, 2019 Do a vacuum gauge test. Quote Link to comment Share on other sites More sharing options...
DJ194950 Posted November 24, 2019 Report Share Posted November 24, 2019 Does it do cold only or even when warm? My 50 Plymouth did the same (dying off idle) after sitting and the ball for accel. pump was stuck and jet for above idle fuel (under the plug- lead?) but my carb is a B&B , yours may be different. My car sat for about 6 months without being started when problem started. Just some thoughts- DJ Quote Link to comment Share on other sites More sharing options...

53 Pilot Posted December 11, 2019 Author Report Share Posted December 11, 2019 Tried again today with no luck. Starts with Starter Fluid, then will idle for a few seconds then dies. Removed air cleaner and watched carb when trying to start. Did not find the float rising and found some leakage from carb body so removed carb. Found some potential leak areas on gaskets so will replace those. Removed carb body from fuel bowl and needle pin is clean and moving easily (fell out when tipped fuel bowl) Thinking now that lack of fuel in carb is due to fuel pump not working. Was not able to work on fuel pump today. (truck is stored 30 min away) Unless the forum believes otherwise I will test the fuel pump next.

JBNeal Posted December 12, 2019 Report Share Posted December 12, 2019 sounds like you are being methodical in your diagnostic procedure...I had a truck become disabled because of a clogged fuel line halfway between the tank and the fuel pump, blew out a pea-sized glob of goo...the giveaway was that the fuel pump bowl would not fill up, but when I filled the bowl manually, the truck started up and ran fine, until that bowl couldn't fill up fast enough... 1 Quote Link to comment Share on other sites More sharing options...
