[QUOTE="Flyer58, post: 429012, member: 18629"] Huh that's strange. I'm not doubting you at all but out of the two dozen or so small engines I fixed for neighbors I'd say about half had black tar in the carb bowl or fuel line that I could scrape out with a screwdriver. Maybe the humidity near Houston does something funny. I also have a boat which sat for 8 years with gas in it before I tried starting it. New battery and a quick shot of starter fluid and it fired right up and ran well. But then I had added quite a bit of Sta-Bil to the tank. I feel certain there would have to be a good vacuum to get any external oil on the injector up past the o-ring and into the line. I just don't see that happening when it's normally around 30 PSI unless they were submerged for a long time and it was some atmospheric condition causing it. [/QUOTE]
