Thanks for the ideas. In response:
- Yes, my fuel tank is vented.
- re: the MSD box, I was under the impression that they are either bad or good. I did not know they could have intermittent problems. Is there a way to test them?
- My fuel lines look like the picture. Looks like a easy, cheap swap. I guess it can't hurt to change it.
- I'll also check to make sure there are no wires that could be touching the fuel lines and sending current through the braided lines. I have already checked my grounds and haven't spotted any problems.
I've now got a short check list of diagnostics to try if (when) it happens again:
- Pull air cleaner off and check to see if fuel comes out of squirters when throttle is applied.
- Squirt starter fluid down carb and see if it starts.
- Pull coil wire from distributor and look for a spark.
- Pull #8 wire and look (hopefully not feel) for a spark.
- Check coil with multimeter.
D-Doug - Good point about the beer/tequilla! Once we figure this out, I'll owe one of you guys.
