Help setting valves on a 225

No offence taken or or intended here - I respect that others "boogaloo" to their own tune!! As I said - just stating my preference based on my experience working in the trade. I have used both methods and made a choice. A quick poll of several of my colleagues (all with well over 25 years experience in the trade) revealed a more or less even split on PREFERRED method - but all agreed the accuracy depends on the man (or woman) with the blade & wrench - not on the method of choice.

My post was NOT meant to imply that there is any flaw or less accuracy in using the engine running method Dan prefers. Dartncharger had requested a little clarification, and some of the info he had was either poorly communicated or simply dead wrong to begin with - my intent was to clarify the procedure he mentioned and provide some justification for my preference.

Valiant1966 - I agree that metal expansion is a factor in valve clearance, but I stand by my statement that the dimension change due to temperature will be insignificant if the procedure is carried out in a timely fashion. In my opinion, there is more inherent inaccuracy in using feeler blades than in 10 minutes of metal cooling.

Engine running or engine off - take your pick Dartncharger. Both methods will work with equal success if done properly.
