Hi Tim, and all,
Thanks for all the suggestions, I appreciate the help immensely! You guys are a tremendous encouragement to me on this, and I'm more determined than ever to find and fix the problem now.
I've run into that low fuel issue before Tim, yes, and try to make sure it's nearly full now. None of the land up here on our old mountain farm is flat, so running side-hill is the norm. ;-)
(Re: those leaning left shutting down - AMEN! I've given up on this country, I'm sorry to say. Unless God intervenes (and we've ejected Him from our society, so why would He?), the USA as we've always known it is done.)
Anyway, enough of that. I tried moving the wiring around with it running today, pushing, pulling tilting the harness tube to the left, etc, and it never skipped a beat. The battery has a homemade strap on it and does move around just a little, but not enough to let the neg. terminal make any contact to ground.
I'm planning on draining the tank again (it's been a few years), making sure the standpipe screen and tank interior are clean. Will also try replacing the gas line, making sure there are no high spots that could collect vapor.
It currently has a slight loop up over the harness tube. Not sure it's causing any trouble, but I'll run the new line under the pipe to eliminate that and see what happens. Thinking I tried that before years ago, but with the 10 minute memory I have now, I'm not so sure.
I'll be sure to let all of you know what caused this when we eventually figure it out.
Again, thanks so much for all the help, you guys are amazing!
