Hard to turn engine over A ford 1929

[gimlegule]

After changing the battery/ground cables They dont smoke anymore, just the starter engine get hot/smokes when cranked to loong, due to to much resistance mechanicly somewhere I believe, will check everything again tomorrow and try tio drive it a bit to see if it cranks easier, it puls and run strong when first started by pulling to start, Climbs jhills fine, but will adjust advance timing corectly withj special key made for that , ignition is Electronic. hard to hand crank when sparkplugs are in.
