Just looks like the puller having a coarse thread will give you less mechanical advantage Speedy.
The one I just used had a much finer thread and with the 12 inch shifter the flywheel popped off , I usually drill and tap the holes all the way through but this one was not right through ,didn't even use WD40 ,the steel centered morse tapers I will discard and replace the flywheel with the alloy centered one .
The GCV 160 coil should fit well on these engines.
