I'm trying to remember if this is one of those engines on which the pulley
nut (bolt?) is reverse threaded to the rotation- it might come off pretty
quick if that's the case. I had mine pop loose as I was commencing to
turning the engine to set the valves- this was on a stand, and I think I
hadn't worked out the proper direction at that point. It was also in the
middle of the night on no sleep, which is probably why I was having a
problem and don't remember much of it clearly
I was thinking that if you had it on a bench you could maybe rig something
to the flywheel and get some quick turns out of it that way. Too bad 'ol
Goff isn't posting anymore, he could tell us all about cranking his Model T
as a young man.
Cya,
Robert
