I am seriously starting to consider a bad fuel scenario, despite having done a remote gas can test.  It's entirely possible the truck was running of the remnant fuel in the pump and carb line and I quit testing before it had a chance to get to the fresh gas.  I should have purged the lines first.  Look at this, it hardly even smells like gas:



I need to try and run it off fresh gas again before I move forward.

I agree, that's the prudent next step.

In other words... if people learn by making mistakes, by now I should know just about everything!!!

Well, after all of this headache I found the issue, and it is indeed contaminated fuel.  I didn't prep the lines effectively the first time I did a remote gas can test and wasted lots of time.

Here's an image of the fuel, fresh gas on right for comparison.  About an inch of water is sitting on top of whatever else is in there:


In all my years working with trucks and motorcycles, I've never personally experienced a bad gas situation.  Nice to learn something new but I have wasted 3 weeks chasing a very obvious problem.

I suppose it's time to drop and purge the tanks....and figure out what to do with 30 gallons of trashgas

Don't beat yourself up.  You know what they say about hindsight being 20/20.  Nothing is obvious until you actually observe it.  Plenty of professional technicians have been stung by contaminated/poor quality fuel.  So, look at it this way, you just earned a stripe!   8)
