Poor idle

Update again:
Did the valve lash while running hot again, and did timing again and it seem to run a bit smoother. Engine ran really smooth at 8 BTDC. As I was starting the lash on 5 or 6, it back fired a couple times and then after adjusting it didn't do anything. Can't find my vacuum gauge anywhere though :( . It seems to run a bit better, smoother, but under load it still bogs a bit. Like the rpms go from 800 to about 500. What causes the rpms to drop that much?

I also removed the ring spacers on the spark plugs as suggested elsewhere .

Still sputters a bit though so hopefully the new ignition will help burn the gas.
