I just completed putting it all together this weekend and took it out on the road for a test drive.
Drive it a few miles, and do a lot of stopping and starting, using my 2nd. to 1st. shifting technique. If it doesn't improve in 100 stops or so, tinker with the clutch adjustment and/or pull the clutch disc and see if maybe the center hub is bent. I've seen clutches get bent and wobbly by letting the weight of the transmission hang on the input shaft while installing it.
