Excellent!!
The spigot you refer to is a vacuum port. Without a cap it's just a huge vacuum leak. Yes, cap it before running again.
There shouldn't be a "classic" lock washer on the front sprocket. There should be a thin washer that's splined for the shaft and that you bend the tabs over to lock in place. It's very thin and shouldn't make a difference as far as threads "left over" go.
Can you put some pics up?

Jim, yeah, that's why I said 'Locking Washer' instead of 'Lock Washer.' There's not enough of the shaft sticking out for the locking washer to engage the splines. I can get it on but I just don't think it has enough of a grip to make a difference. BTW, you know what the torque is supposed to be for this nut? Someone earlier said 95 foot pounds which is enormous...
I'd sure be interested to know why idle is higher with the vacuum port open vs. covered.
