Super Tigre G-90 for parts


I bought a used ST G-90 Chinese made engine today at the wram show swap shop.

Well when I got home and gave it a good look see, I found that the prop shaft/crank is bent.

There was no way to really tell until I put the spinner back plate on. I initially thought it just wasn't sitting flush against the thrust washer. Then I realized it was sitting flush and that the prop shaft/crank was bent.....total freakin bummer.

Forget about spare parts for these things....on back order for years, everywhere.

Does anyone have one that would be good for just the crank shaft?

Thanx Reacher: I was considering buying a ST90 for one of my planes but after your comment and then checking Tower website and seeing the majority of replacement parts on back order, think I will go with good ole OS.

All righty Oh...we're back in the game...Shoo got the Crankshaft back into shape!

To show my appreciation I put a nice stick of chewing gum in the box. J/K

He gets to choose which one of these brand new Trans Mitts he wants!

Just put the order in for a new piston ring and then we'll see how this thing runs.

I think what the guy did was buy a new engine and stuck the brand new carb and muffler on this engine to make it look good. That carb is gonna do me justice!

Thanks Shoo!
