Sounds like your carb is way out of whack adjustment wise. What size main jet is in there? what is your a/f screw set at? and what is your needle position? Also you should make sure there are no cracks in you intake or vacuum hoses, make sure your vacuum petcock is working properly, carb is getting enough fuel, carb float height is correct, etc.

Also for valve lash, you don't need to crank it down on the feeler gauge too hard. Should still be fairly easy to pull the gauge out once you have the adjuster nut tightened.
