First you need to find true TDC. Use a stop and bring the piston up to it and record the reading (i.e. 10* to the right of 0). Now go backwards till the piston hits the stop. If the reading is the same (10* to the left of 0) you have TDC. If not adjust the pointer (or move the wheel) till the #'s are the same on either side of 0 TDC.

Now place your dial indicator on the intake liffter. Bring the lifter to max lift and zero the indicator. Now rotate untill you read .050 and record the #. Rotate back to 0 (max lift) and continue till you read .050 the other way. Record this #.

Add the 2 #'s togheter and divide by 2 and that is your intake CL.
