O'CT has it dead in the crosshairs IMO - .002" both intake and exhuast, you'll most likely find the intake valve needs more adjustment than the exhaust. A pic of your 84 CT would be appreciated...
X3...
You might even go .003" intake/.004" exhaust, temporarily, if you have any doubt as to whether or not they're too tight. If that corrects the problem, you've isolated it and can then readjust the valves to factory spec. If the problem persists, then it's time to check fuel flow to the carburetor as valve clearance would be completely ruled-out. Just remember to readjust the valves, if you use this old-school diagnostic "trick".
