Got it pretty much done. I did not find stuck rings as I suspected. The rings didn't look bad. The new ring had about .024 gap. Honed the cylinder and got all the rings in by the book. Found the rod in backwards according to the book. Found two rod nuts, their washers and a screw in the crankcase.
I didn't find anything that looks like it would have been causing the blue smoke. I'm wondering if the dipstick is not reading correct making for too much oil.
How much oil do you guys put in one of these engines at oil change time?
I have to get some fuel line and plug off a connector on the fuel pump. It has the wrong one with an extra input that needs plugging. After that I'll add oil and start it up. I expect that it will still be a mosquito sprayer though.
Thanks for all the help.
