Starting new thread for same old problem.....

Where did we put the fuel volume check for the G749?

I see the trouble-shooting par 133, pg. 244, where it states "Pressure should be 2 1/2 to 3 pounds". ....TM 9-8024.....but that volume test eludes me.

It's a simple test where you turn on the fuel pump, fill up a measuring jug over a period of time and should come up with a volume. It could have been on a PM magazine but if anyone finds that procedure, can we post it up please.

In this video we can hear a 'miss' but it wasn't until dark when we could see some arching from the #6 plug. It always seemed like something simple once we figured it out. Drifting in the dark is a good way to test things. You just need some snow!

are you meaning the actual resisitor or the condenser at the points?

Now that "drifting" looks like a lot of fun !

actual resistor

sometimes after a january thaw the lower corn fields flood and then as they drain they freeze over leaving a few inches of perfect ice on the ground.. Back when my M38"A5" had very-wide tires i would take it out to do 2WD ice ballet , get a 500ft running start, crank the wheel and let 'er twirl until the ice ran out , usually another 500+ feet .. Sometimes the spinning lasted long enough you could get very dizzy .. i would have to quit when i started to feel sick but it was a blast .. the 80's were fun like that .. Had i had that jeep in the 70's, well, that've would've meant more years of fun and mayhem !

Spent the afternoon trying different things, still no change. Truck will fire right up and idles great. Reev the engine, sounds great. Drive 2 or 300 yardsm starts cutting out and sometimes stalls. Let it set a couple minutes, can usually get it back home about the same.
Today we checked out the "primary circuit resistor". When I changed the coil Friday evening I thought the wire to the coil seemed like it was about ready to break off. But that was not the case. The wire is in good shape, only the insulation slips around a little on it and makes it seem that way. Also checked the continuity with my multi meter and it seems perfect.
Rechecked, and did reset the points. They were just slightly a little over .022, now are a bout as perfect as I can get them.
Took off the second new fuel pump after visually looking at the flow, wheich seems low? The old one seems far better. Drove it and got around 1/4 mile, before it too gave up the ghost!
So we got it home and removed the center floor pan and inspected the vac lines from carb to dist, and the flex lines at the dist. All seemed just fine and no signs of wear or deterioration?
Guys, this truck starts right up and idles and sounds just great. Even can reev it up over and over when sitting still. Then try and go down the road and usually can't get over a few hundred yards and it starts cutting out. Up a slight grade, but once it starts that it will hardly go on the level?
I do not have any idea what to do??
