Out of balance and vibrates very strong to point of dangerous
There is a piston that has a bad vibrationIt will need to be taken apart and every part in the piston area will need to be weighed and checked with weights of other pistons and balanced.It will walk right off the table and start a house on fire if one was not careful .It was expensive enough to where it should run perfect and not need rebuilt that is for sure!!!

Absolutely excellent Sterling Engine
The engine is very well made and runs impressively. This is my second from this manufacturer and I 100% recommend it. I gave it as a professional gift to a valued customer and it was immediately loved. Quality is just beautiful and sturdy.
