Bought this in June last year. Ran fine all year. Stored it inside for "most" of the winter, without winterizing. (Mistake # 1, now I know better)
Ran one time this year with old gas/oil mix from last fall. It ran with a little coughing, but ran all day. (Big mistake #2)
Next time out, it wouldn't start at all. Replaced the plugs, which looked like they had gas/oil mix on them, and pitched the gas. Ran in a tub yesterday with new gas/oil mix with a little seafoam in it. Ran fine for twenty minutes or so, but with some blue smoke.
Today, it wouldn't start at all when I got to the lake. The fuel line had dry rot in the primer bulb, replaced that. It almost started, but died after 2-3 seconds w/ no restart. I may be overpriming or flooding as the carb and plugs seem to be wet with gas.

time for a carb cleaning, crud in carbs, if float needle is work you cannot over prime, with the fuel bulb.
