Hey everyone.
I haven't had much luck with this motor as you can see from my previous posts. Still having the same problem. Doesn't want to keep running, has pretty much no idle and pops hard when I try to give some more rev's. I took her apart today and I noticed that the lower connecting rod was covered with black exhaust crud!! When I looked the cylinder head, lower cyl had black crud and upper had none (chrystal clean). Spark, fuel and the usual stuff is checked many times..
Last year when I bought her I tried running in sea, barely got the boat to plane, had low power and anything below 2000rpm would make a hard pop and then stall..
So what do you mechanics think about all this?
Thanks for help!
