Default Re: Valve adjustment question

hello 5tractorguy, this is Lewis Matkin. The factory manual says that the valves were to be set hot at idle. Specifications are 0.012"H for the intake, and 0.018" for the exhaust. I have also set the valves cold(for obvious reasons--OUCH!) by adding 0.002" to each measurement. This method has worked well for me in the past. I hope this is of some assistance.

Cordially,
