I should have clarified, the eighth-inch difference is the diameter. For the lift difference, I used .0625

With an adjustable valvetrain, it seems to me like the extra adjustment would take out any pushrod slack and the full lobe lift would still be imparted on the lifter and pushrod, which would translate to full valve lift.

Gotcha

Pulled the carb off and the intake walls and floor were covered in a gas film. This was with the mixture screws 2 turns out.

Going to definitely be interesting to see what the problem actually turns out to be.
