used a 12V battery with 6V coil. starter is 6V and from what i have researched here it should be ok. actually should turn the starter a little faster.
re-read my initial post and it is more like 3/4 turn is hard by hand and about 1 - 1/4 turn is smooth.
on monday (son has soccer tourney this weekend and no time) i am going to do some more investigating. gonna mark the crank pulley and start from #1 tdc so i know exactly how many turns i get before it gets difficult to turn and take the head off and see what the pistons are doing. probably will take oil pan off too and see if i missed something.
