Roger, If she'll burn off the fuel, during the "No Start" situation, You definitely have a fuel issue, not spark.
Before you get involved with the carb (maybe soon enough!)
Lets investigate fuel flow on its way to the carb. This might go best, if done the minute that the beast will not start!
Soon as you cannot crank it be ready to do the following quickly, this may require some assistance:
Snatch the fuel line loose real close to the carb, attach 2-5 feet of new fuel line to the loose line (Steel line?).
Throw the other end into a Jar/ Jug that will hold at least a gallon of fuel (Just so it don't overflow on you)
With a spray bottle, mist fuel into the carb
Have pal fire it up,
You keep it running for about 30 seconds, with the spray bottle
After 30 seconds let it die
Measure the fuel you just got in the jug
Come back with results
We want to know if there is enough, or any flow to the carb
If too little fuel gets in the jug, we will continue toward the fuel tank till we find the problem
Same way, one item eliminated at a time
This may/ or could be:
Bad pump (Electric/ Mechanical?)
If add on electric pump, what kinda fuel pressure you got? Use Gauge, no guessing. Whats the carb require? See paper work.
Fuel filter restricted, Again? (Mega trash in tank)
On the suction side of the fuel pump,
A old crappy rubber line may be "Sucking Flat"
Crimped line(s) somewhere toward tank
In the tank, the pick-up may have trash s. Ucked to it.
Heck, the darn fuel tank may not be venting, pop the cap, see if it s. Ucks air!
If all is well on flow, We will investigate the carb
Can you send pics of carb?
This start just after carb installed?
Specifically, show pics of n. Ipples you "Capped Off" on the carb
Do you still have carb paper work? Interested in "Bowl Vent(s)"
Waitin' on results!
Remember I'm a Jeep Guy! (Maybe you could get a CJ, and we would have no problems!)
