Morning folks from North Yorkshire , England.
Took out a Magnum 36 the other day to install into one of my profiles.
It’s a converted ex R/C motor , a nylon Venturi , blocked boost port , with a single head shim.
Always kept boxed , clean and well oiled , whilst in dry storage.
When I tried to turn it over it ‘jammed’ , didn’t want to turn over.
Took off the cylinder head . Turned over perfectly.
No bearing issues.
Put the head back on , and bingo , didn’t want to turn over.
Any suggestions fellas ? Any contributions much appreciated.
Robin.
