Ok, update...
After all this, figured it was a stuck float due to carb gunk. Sea foam seemed to help initially, then got sticky again and spittin' gas out vent tubes. But only at idle.
Friend of mine invited me on a Sat am cruise with a group of Harleys. I figured, maybe it would burn out some of the gunk to go for a couple hour cruise at highway speeds and since it only spits at idle, cruising should be fine, right?
Wrong.
After only 65 miles I was into my reserve and once in the reserve it started to spit gas at highway speed. Ran bone dry 10 feet from gas station pump
Friend and broke off of group and returned home. Next day, I was telling some friends at church, and a guy says, "well your carb bowl has a drain plug. Just flush some gas through it and knock the crap out...here give me your key, I'll go do it for ya."
He did it. It has been running great all week. I added a couple more ounces of sea foam with tank fill today. I'll Keep checking mileage to see if there's any improvement. Any other suggestions for better gas mileage?
