Checked it while we were on the side of the road. It's definately pumping. I 
have a pressure tester if need be, but I don't think thats it. Thing is, you 
have to see what the pressure does right before the stall. Pressure drop, then 
stall=loss of pressure. Stall, then gradual pressure drop=normal for a 
mechanical pump.

Oh I member. So if it pumps gas at all it works but how can you tell if it 
works well enough?

The fuel pump can be tested while cranking.(not starting).Attach a hose to the 
fuel pump outlet to a bottle.Crank the engine over a few times then check the 
bottle for fuel.Make sure the coil wire is disconnected at the coil.It has 
already been determined that you have spark,member the skin test?

It's possible but the carb has only 400 miles on it. I am thinking fuel pump 
but I suppose it's possible.  Problem is I can't get it started to really check 
the fuel pump

Sounds like a possible stuck needle valve not allowing the fuel bowl to fill up 
as you drive, since it conks out after 5 minutes or so. then refires.
Is it a 30/31PICT Carb? There pretty straightforward to mess with. 
I'm thinking that or fuel pressure issues.
I will say the BEST diagnostic tool to have is a fuel pressure tester to check 
the fuel pump pressure bteween pump and carb inlet.  Just about any fuel pump 
you get 'new' today is pushing way past 3lbs...
Needs to be between 2 to 3lbs,no more or you'll blow fuel past the needle valve 
and truly have hard start issues with fuel being forced all over the place.
Any FLAP can order one, just run a tee in it and plug it in between pump and 
carb.
 
I'm gonna bet fuel pressure might be your issue, but get a carb rebuild kit, 
cheap and easy to do as well.
Sounds like your ignition systemhas all been worked over well.
Now one thing I have seen before, its crazy, but a coil can get super hot and 
cause issues to after a brief period of running. Have you swapped out coils? 
Just another idea...Make sure you get the coil with the internal resistor as 
well.
 
best of luck.

do you know that you have spark at the end of the plug wire? if there is 
nothing there we should start on the electrical.From what you discribed it 
sounds like the electrics are okay.It's not likely that you have electrical 
problem because it will run for awhile before stalling.The hard restarts could 
easyly be a fuel problem.

Thanks Chuck, I did remove the fuel pump to measure the piston and did not 
notice anything odd but then again I didn't know what I was looking at - I have 
been the happy care free owner of a late model FI set up for 18 years and am 
like a caveman lawyer when it comes to early carb'd single ports...

Okay. Be sure and check the fuel pump flange.(The little bakelite thingy under 
the pump)The push rod should move freely.Some of the bakelite flanges would 
react with the oil sweel up and sieze the fuel pump push rod.That probably is 
okay but it still needs to be checked.Also check the pin in the fuel pump. They 
have been known to work out.
   I'm at home so if you want to talk give me a call at 903 677 3256.This 
shouldn't be to tough unless it's happening to you.

It is a known good engine rebuilt less than 300 miles ago. 1600cc single port

The fuel tap should have a screen attached to it.It is a screen tube that fits 
on the tap.A quick check would be to see what kind of fuel flow you have from 
the tank.If you have good flow to the pump check the flow to the carb.
  Is this a known good engine or are you working on someone elses trouble and 
does it have the 36hp.

So if I remove the fuel tap I should be able to remove the screen from there? I 
have this afternoon off so I plan on switching out dizzys but it seems like an 
electrical issue that is preventing it from turning over. If I turn the key it 
goes "wrrrvump" for 1 second then stops. Like it's not getting enough juice. 
i.e. open circuit, too much resistance. I'll have to wait for a helper to check 
fuel pressure.

Definitely check the sock screen in the tank.

I have had an intermittent starting issue since I can remember (1 year at 
least?) so anyway, after waiting 10 seconds after the 1st attempt it would 
start up.
Saturday I picked him up from the body shop and it took 5 hours to get it 10 
miles into my garage.

The engine died 5 miles from my house and I pushed it into a parking lot where 
Robb noticed the center post on the dizzy cap was broken, walked to FLAPS, 
replaced drove to the gas staion 1 mile from my house and left it idling as I 
was pumping gas into the gas can it died, i spent the next hour tring to get it 
started, replaced the points, condenser and it took 10 tries after that (with 
jumper cables) to get it started. I got all the way to the driveway and while 
the door was opening it died again. 2 hours later it barely started and I got 
it into the garage 5 hours before the hail storm : 0

I never replaced the rotor so I did that last night, started up and idled for 5 
minutes then died. I started it back up and it idled for 25 minutes and I 
thought it was fixed.This morning I realized it is not fixed. 

I have spark, I checked the battery and it was charging (2 weeks ago) it has an 
8 v battery but the regulator has been adjusted for that and it  is a brand new 
wiring harness and I have cleaned the grounds for the battery and tranny ground 
and I am stumped. 

the November show is a week and a half away and this is the only thing left to 
do on him. This weekend, I finally got the  @#*% fixed that was done in Ennis 
and received the last door panel from Lenny 11 months after requesting a 
replacement...
