Hello,

I just received a new engine. As with all engines I receive I opened it up to check for burrs and left overs from the machining process.
Well, this one has got a lot of left overs in it... the stuff is everywhere!

So normally I just take the engine apart, wash everything thoroughly, oil it, and put it back together.

This one has got me baffeled. I am unable to remover the liner.
Normally heating up the engine case slightly with the hot air gun is enough to free up the liner. Sometimes when the liner fits tight it is necessary to cool down the engine before heating up the top of the case.

But this one won't move, no matter what I do...

BTW, the engine is an MVVS GRRT.

How do you top mechanics solve this?
