Hey all,<br /><br />My 1979 Mercury 40HP was running just fine before i Pressure washed the engine.<br /><br />Last night I pressure washed the engine to clean it, as it was covered in grease/oil...<br /><br />I closed the Choke to prevent water getting into the carb.<br /><br />Now that i've pressure washed it, it won't so much as fire. I don't know if water still got into the engine somehow, or what, but for it not to even fire now, doesn't make since.<br /><br />Anything anyone can suggest to help is apperciated.<br /><br />Thanks,<br /><br />-TheChad

Yeah, I will check it for spark, but i need a 2nd person, obviously i can't turn the key and see the spark at the same time... So i'm waiting for my wife to come home from work..<br /><br />What do you mean by "Try a little fuel mix in the carb throat"?<br /><br />Are you saying to pour a little fuel into the front of the carb?<br /><br />I sprayed carb cleaner in to see if that would help, and nothing...<br /><br />Thanks,<br /><br />-TheChad

carb cleaner will do the same thing, just will help displace water in the cyls

I don't know for sure, But it doesn't look like there is any spark...<br /><br />I was standing about 4 feet away though..<br /><br />I took the top plug out and had it resting against the motor framing, I turned the engine over, and didn't see any spark...<br /><br />-TheChad

It definitly doesn't have spark.<br /><br />What should i do to figure out why I have no spark? Is there someplace i should start, or something i can test?<br /><br />Thanks.<br /><br />-TheChad
