Ray,

If you leave the pulley off does it still do it? All the nut does is
hold the pulley in place. Are the bearings seated correctly front and
back? The only thing I can think of is that if you have the pulley on,
and the bearings aren't seated all the way, your tightening everything
up to much and it's pulling the flywheel tight against the rear main
bearing.

Charlie,
Thanks for responding.
No bolts rubbing. I removed the pulley and tried again, no difference.
Removed the rockers thinking maybe something there was binding, same
thing. Pushrods (and lifters) moving normally. Everything inside is
spinning, tightly, but I expected that from new bearings, pistons,
cylinders. But if I tighten that nut on the end of the crank where the
pulley mounts, it all locks up.
Only thing I can think of is a crank free-play issue but there is
absolutely nothing about this in any of the lit (that I can find) and
when I posted the list about this, all the responses I got were the
same, including from experienced Guzzi motor builders - don't worry
about it.
This motor was torn down completely. The rebuild didn;t seem complicated

at all and no spare parts were left. I'll teasr into it this morning and

let you know if I find anything.

Hi Ray,
The bolts of the crank pulley aren't rubbing against the timing cover
are they? Trying to think where else there could be a problem. How far
apart did you have this engine? Cheers, Charlie.

Happy Holidays y'all.
We miss the snow on Christmas day but damn it's a beautiful day here.

Was assembling the top end last night (again, don't ask). When it was
together and ready for valve lash adjusting I used the generator pulley
nut to turn the motor over. As soon as it was tight, the motor refused
to turn anymore. Loosen it up and it turns by hand from the flywheel.
Tighten it up and no-go. Dreamt about this last night, dammit.

Any ideas? This is why I was reluctant to put together without any
regard to crank endplay, although I don't know that it is the culprit.
