When engine is new / tight I pre-heat the engine nice and hot with hair dryer - this expands the sleeve and makes it easier to start - also less stress on conrod/crank etc. If you still have problems after preheating you can crack the glow plug somewhat to allow some compression to escape (tighten once started)
You must have a little starter box ? The box I have has not had a problem with 2 STS .12's and a STS .21
(and a few other engines).
Been there done that, used a heatgun to try expanding the sleeve, helped a
little, but it pinched so hard I have worn out the flywheel when moving
it from the TDC when pinched *edit* using the same procedure as mr. nightmare describes below, that why the flywheel is now worn out */edit*. Yes, my starterbox is not big, but strong enough
to spin eventhough the engine pinches, and pinches harder than I (100 kg) can push it down. I will try loosening the plug when starting it as soon as I have got
a new wheel for my starter, but it does not explain why the engine will
stop dead (and pinch again) after a lap or two. (with very rich settings)

Then I guess you are Tommy B? congratulations to the victory! Always nice to hear the engine has potential, now I just need mine to get going. What do you mean by polish, or more precisely what have you polished?
