engine and drivetrain Please Help!

1602 with weber 32/36 manny choke.

 

when i choke the engine, it starts up, immeditely revs to 2k, then dies right after. 

 

if i am in the engine bay, i can shut the coke all the way with my hand, and the car will sort of lightly rumble for a few seconds and die off, but if i proceed to give it any throttle it dies. 

 

also if i try and open to choke a little it dies.

Fuel supply? Sorry I only know tiis but try turning it over with fuel hose in container (no spilling) and coil disconnected (no spark). See if the fuel runs fast and continious.

Hope that helps.

i have purchased multiple mech fuel pumps in the past, and none of them work, so right now i have the mr. Gasket 42S electric fuel pump , which says does ~1-4psi, with the spectre manual regulator. 

 

i was told the 42S was a 'pulsating pump' so the fuel is not continuous, but i have read other articles about people using this same pump with no problems. 

 

would fuel line ID make a difference?

If you are running an electric fuel pump, can you run the pump for about a minute before attempting to start the engine? If it runs longer before stalling it sounds like it is starving for fuel for some reason, pump, line kink, filter, or internal carb issue. Line diameter could makea difference if it was really small, but it would still idle. Pull the fuel line off of the carb and run the fuel into a jar for 30 seconds and see how much is being delivered. If flow is ok the perhaps needle and seat in the carb might be stuck? I did have a 2002 with power brakes once that had a blown diaphragm in the booster and it wouldn't run except of the floor.

i usually wait about 15 seconds once the electric pump is on, before starting the ignition, and it usually just revs up a little higher before it dies, ive gotten it to run and idle before, but today it started this issue.

 

my major issue is i dont always know how much fuel is in the float, and i feel like i cant tell the difference of fuel starvation and fuel flooding.

What carburetor system are you running? Depending on the carb your using you may be able to fill the float bowl manually and then start it. If the problem goes away (until the carb runs dry again) then you know either the fuel is not being supplied by the pump for some reason or the carb needle and seat are not opening to let the fuel into the float bowl.  I would also still check to see if the fuel pump is actually pumping fuel by disconnecting the fuel line to the carb and letting it pump into a catch container and see how much you get in a specific period of time. Please remember I am only assuming it is a fuel delivery problem, it can be ign, mechanical, electrical or something as well, it just sounds like fuel so that is a good place to start.

I just re-read the first post and see the Weber 32/36. The Weber can be filled by squirting some fuel into the vent slot on the top of the carb next to the throats. I cant seem to get an image to post here so here is a link to an image online.        http://ozdat.com/forum/viewtopic.php?f=28&t=30911    The vent slot is the circled part on top not the numbered parts. This carb is not exactly the same as yours but it is a 32/36 and is basically the same carb.

Are you running a idle jet with the solenoid shut off valve? It sounds like you don't have any idle circuit once you have used up the extra fuel you get from the choke. If you are running the solenoid make sure it gets power when the key is on and not just when the starter is being used. If you are not running the solenoid style idle jet then I suspect you have something blocking the jet or passageway.
