Nothing happened in between trailering home from the lake after getting it back from the tech. I brought it out the next time, it started rough but then Smoothed right away. I idled up and down the river, throttled down all seemed great. On the way home that day it stalled while going at idle speed, didn't start right back up, but when I got going I just headed home. This last time, as I mentioned, it started rough, stalled out quickly, was eventually able to get it in gear with the throttle quickly put down, but the whole boat was shaking. Then all of a sudden it kicked in a took off. Went up and down the river high speed, good throttle response throughout range, then died at idle speed when I slowed to fish. Hard starting again, let it sit. Got it going and in gear, same thing. Got it back to to do I and left it at idle, idled for a minute or two then it died out. Put it on the muffs yesterday after draining the carbs and wiping what I could down. There was residual oil in the carb air openings right in front, and the plastic air of has some oil on it. Started it up, idled ok at 1000 rpm, then suddenly dropped to 500 rpm and stalled. Started again easily, idled ok at 1000rpm, and even settled to 750 ish rpms and I killed it. I saw the non-vro version of the pump on eBay for over $300. Could it be a bad cylinder? That would stink. Can you talk me out of that likelihood (please)! Don't really have the money for a repower or the know-how for a rebuild.
