Title: Update and Carb Question
Post by: DENNIS P NOLAN on May 26, 2021, 06:38:26 PM
Thank you to all that have helped me via this platform-
Update on my 39 P-8
New: Gas tank-plugs-points-condenser-cap-rotor-starter-in line gas filter-
I tried starting the car today (it's been a few years-thus the new gas tank) and
it wouldn't start. Points gapped to .020-
I took off the top of the carb-(Carter) and the float bowl chamber was bone dry.
Gas is at the carb- as there is a glass bowl just outside of the carb-so, fuel pump
is working. The float moves a little and the needle valve is not stuck-no varnish anywhere.
Since the float moves a bit I would think it would be enough movement to allow gas into
the float area-but nothing. I took off the gas line and glass bowl fittings and blew all of that out
there was no obstruction.
So, Even with minor movement of the float- should I bend the float up slightly to get gas into this area?
Somehow that doesn't seem right either.
Thoughts?

Will it try to start if you pour a little gas in the carb. It might need a little help.

There are a couple things going on. Fuel in your fuel pump glass bowl does not indication that the pump is able to pump fuel up to the carb. It does indicate that the pump can likely suck fuel from the fuel tank. Two different things. It may not be pumping out.

Having a spare set of hands helps here.  Remove the fuel line where it enters the carb bowl. Hold it in a bucket. Have a friend crank the engine over. Is fuel pumping out of the fuel line?
If yes, then fuel pump is working. Next inspect bowl intake valve. Take it apart. Junk in there?
If no, you are either out of gas, have a plugged line, or fuel pump is unable to pump. Don't trust the fuel gauge in the car.

For further testing consider using a piece of hose. Maybe 2 feet long or so. Take cover off float bowl.  Put some gas in a smaller-ish empty, dry, plastic water bottle. Attach hose to carb bowl intake check valve. Get a small funnel. Hold hose up vertical.  Pour gas from bottle into funnel/hose. Does it flow into the carb bowl thru check valve? Does the float stop incoming fuel when bowl is full?
