Happy New Year!
I know it's a bit early for an Easter egg hunt, but that's what I'm on trying to sort the problem I'm having with fuel.
I've been told "It's always something with that car," and this time, after 4 months running beautifully, I hit the snag of the 5-year-old Optima batteries giving out (no longer fully rechargeable) and demanding so much charging that they burned out the top contact of the voltage regulator. I bought 2 new batteries that did not tax the system and Brillman honored their warranty beyond the call of duty and replaced the VR. So everything should have been fine.
But then I started having fuel problems. In the one an only 2020 issue of the Oregon Clipper magazine is an article on winter vapor lock. I read it a few months ago but it didn't stick in my brain. I showed the issue to my Sis and she suggested that the problem was winter-blend gasoline. I of course blew this off. I re-read the article this morning and I think she has something.

WINTER BLEND GASOLINE evaporates easier than summer gas. The bubbling in my fuel filter could be an indication of winter vapor lock. The car only shuts down when the engine gets hot (not that hot, just when the thermostat indicator is straight up - normal operating temp).
It's hard to admit that a sister who teaches art knows more about car problems than I do. Now to make the Dave/Don adjustments to the auto choke setting, ignoring the manual. I might try my hand at adjusting the metering screws, too.
