So, I was a bit too optimistic with my earlier post. The machine ran good for a couple of hours, then back in the crapper. I called the service department and the guy said maybe it was an air-leak, so suction might be affected. I decided to try to change the fuel line, so I dropped the cover under the machine to get at the inlet to the transfer pump, and being underneath the machine, I saw that the nipple for the fuel line was part of another banjo fitting. It was at that moment that I realized that Delmer nailed it in his June 13 post. I'd been told about the screen in the banjo bolt, but never found the right one (I'd been checking all of the banjos that I could get to from the top of the motor. I guess, in hindsight, that makes the most sense to have the first point of inlet screened, which it was. That sucker was plugged full of crap. I cleaned it out, blew it out, and put it back in service, gave the manual plunger about 20 pumps, and the machine fired back up, and ran all day.
