One, setting for that long may not be good thing. But as previously mentioned, rotate by hand? But with my B which I use every week to mow with, if when I shut it down and the crank stops ??? might be top dead center, or perhaps bottom dead center, I get the same thing. With the ignition off, I'll put it in 3rd gear, grab a couple of tire lugs and rock it foward a couple of inches. When I take it out of gear, turn on the ignition and hit the starter, will turn over with ease.
Setting that long though...not the best thing in the world.
