My Craftsman power washer has a Tecumseh Enduro overhead valve 6.0 HP engine. I bought it used, but I have always used the “recreational” gas, and it usually starts with no big issues.
This Spring I got it out and it started up pretty easily, with just a bit of gas spritzed in the carb. My wife was washing off the deck and wanted to stop for a bit to move things around. I gassed it up again, and then it wouldn’t start again. Not really even try more than just slightly. I even tried ether, and that wouldn’t help, either. It’s got spark, gets gas. What could be the problem? And even if I had flooded it (which it probably was by the time I got wore out from pulling the cord), several weeks later I took the power washed pump off and tried again. Still won’t really try.
