I inherited a 290 from my BIL when he closed his shop last year. Customer brought it to him in pieces in a recycle bin, needing a p&c. He was gonna pitch it but I saved it, figuring it would be a fun project. Picked up the parts and cleaned everything up today. Problem is, I'm not really sure where to start as I have no frame of reference to work by, not having torn it down and never having rebuilt one before. I'm not totally stupid as I used to rebuild model airplane engines as a kid but there's more stuff and parts on this and some I have no idea what they are or where they go.
Was thinking I'd get started and ask questions as I go. I'll post pics as I progress.
Will use 2cycle oil as assembly lube inside the motor.
I figure I'll start by replacing the piston, then load that into the cylinder. Next, drop that into the lower crank case which is still bolted into the plastic case.
I don't have special tools to deal with the rings - any tricks to doing it, poor-boy style?
The bottom part of the crank case looked like it had a silicon type gasket as there was a piled of goo I brushed off (also looks like the same goo was on the crank bearings). Is there a gasket I can get from the dealer or should I just use some permatex?
Anything I'm missing in order to get to this point?
Where I'm starting from. I'm sure there is missing hardware (some parts are buried in this pic).
