Default Re: Model A motor froze-up

I have removed the spark plugs and sprayed the cylinders with Kroil, soak, and repeat until lose. Be sure to spray the valves. One can also place a wood dowell dow the spark plug holes and tap, tap, tap. Takes a bit of time and lots of soaking but has worked for me.
