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.

while it may run..it would probably use oil....and maybe even piston slap.....
Its a crapshoot....good crosshatching may help....
Did you check the ringgaps on the rings you took out...I'm guessing they were about .050...

No slapper, I didn't think to check the old rings while I had it apart. All's well that ends well though, because it doesn't smoke any more.

I put one quart of oil in for frear of the dipstick not reading correctly. I read so many situations in the troubleshooting section of the manual that were due to overfilling with oil, I want to know exactly how much oil I should put in. I think the dipstick is not right.

How much oil should be pourted into an empty crankcase of a Tecumseh OH160?

Thanks to all for the help.

I found it in the Tecumseh Engine Tech Manual.

The OH160 takes 52 ounces of engine oil.
