I knew it was all going too easy! The top end seized lightly, everything just generally corroded from sitting for decades untouched... likely in the Minnesota cold. When I tore down the top end after finally getting the pistons un-stuck (thank you Kroil, I love you even more now) I found out that the crank needs a rebuild. The LHS conrod is super super stiff and notchy, indicating a bad bearing... likely just corrosion... but it is not really coming around, even after soaking my 'special cocktail' for a couple days now. Better safe than sorry.... I'll replace the bearings, and check the specs on the top end and go from there. I will probably end up doing the top end too. Now's the time!
