Further on the crank bushings – measure things to eliminate the guess-work. You want to turn "a tad loose" into knowing exactly what your clearances are. Those bearings should not have any more than about 0.003" clearance, otherwise it will be difficult to start due to sucking in too much air around the crank journals. If thee clearance is great er than 0.003", you can get by with applying grease to the journals when you assemble it, but the effect the grease has on startability won’t last forever.

Best,
