Does a glow engine get tighter as it gets run in? i have a .28 dynamite engine in my savage and it never had alot of pinch, if i was to take the head off i could spin it over by hand with my wand starter . after letting it idle through most of a tank today. the engine got way tight and now if i take the head off and try turning it it pushes the sleeve a quarter of the way out of the engine. i figured the pinch would lessen the more it was run.
Why would you idle a tank of fuel through an engine - is this a car thing? I'd never do that to an ABC aircraft engine - what is the point of doing so?
