Purchased a supposedly never run engine (Enya .049) --- not true!

Purchased an Enya .049 from R/C Groups and the title was "ENYA .049-II T.V New In Box with muffler"

Well I received the engine yesterday (May 16,2022) and it was gummed up and not able to rotate.
I heated up the engine and was able to get the piston to move.
While it was "hot" I removed the cylinder head and as I expected as the engine was not moving freely that it really was run and for some time.

The top of the piston had plenty of carbon on the top of it.



The wear on the piston is very evident:



And the back plate had evidence of it being run and that the engines was mounted onto the firewall by the marks on the back plate.



One last thing was the piston is suppose to rotate freely like a Cox piston and con rod.
Well they were gummed up as well:



So,
I cleaned up the engine, freed up the piston so it spins freely, fixed the rubbing of the crank on the backplate, removed the carbon from the top of the piston, and rebuilt the engine with all new gaskets.

Piston without the carbon buildup:



Now it turns freely, and looks like a "New in the box" engine with muffler.


For $156.00 it was not that bad, plus the cost of new gaskets ( $1.83 for backplate and $1.67 for carb.)
