Last week my motor was acting a little funny in the midrage It would miss and spit and sputter and It would barely idle. The only time it ran smoth was at about 80% throttle all the way to WOT. No where on the low end would it run smooth. I had to run WOT or idle around with it smoking like crazy and spitting oil.
I changed the plugs, put some gas treatment in the tank (2 times) and it still didn't help. Needless to say I took it to my motor guy, Thought maybe there was something more serious wrong with it like reeds, or a bad cylinder or something. When I went to pick it up I fully expected to hear that I was going to either need some serious repairs or a new motor.
Turns out, the carb was stuck. Apparently there was some junk stopping it up and it was running on only 1 cylinder the last time I took it out and even then the one cyl that was firing was missing (the time before that it was in and out) . That explains the oil all down the motor. The top Cylinder wasn't firing at all, the fuel mix that cyl was getting was just spitting out the exhaust. It was a mess.
He cleaned it, out and I picked it up today and went straight to the boat ramp. It was like a whole new engine. Smooth, quiet and alot more power. It jumped on plane quick, before it would sputter a little till the rpms got up then the 2nd cyl would kick in around 5,000rpm. Top speed was not much higer than before. I could go 30-31 before and today hit 33mph for just a second or so on GPS. And I was able to run on plane as slow as 15mph I like to run on plane at about 20mph which is about half throttle. Before it would not run slow on plane. WOT or idle was all I had, so I was buning though gas quickly. Toda I cruised at around 18mph to 21mph for over and hour in one direction and then about another hour at 25mph on the way back. From Middleburg, FL to the St Johns river at St Rt 17 near Flemming Island and back with a few dtours into some small creeks to look for gators. I barely used 2 gallons of gas.
Very happy I didn't have to spend a lot of money!
