I still like my Thermoquads, but....

I'm still emotionally and financially invested in my Thermoquads, but did you ever notice that if your TQ-equipped Mopar sits for awhile, the carb won't work right? The vehicle keeps running out of fuel. It will run fine for a minute or two, then die from lack of fuel, and then start back up again after a few minutes and do the same thing.

So far I have found two reasons for this:

1. Fuel inlet (float) valve stuck or obstructed due to residue left by our crummy gas; and

2. Top cover of the carb has loosened up so the carb idle circuit isn't pulling vacuum.

3. (?) Idle circuit obstructed by crummy gas residue.

Would anybody have more reasons that I should check out? I really need to be able to fix this when it happens!

Can I clean out the idle circuit without pulling the carb by removing the idle adjust screws and spraying carb cleaner in there?

Or is it time for me to disassemble and clean my TQ?

Kindly edumacate me on this guys. Thanks a lot.
