You are absolutly correct in that you should check to make sure the timing marks and the index scale is accurate. You don't have to do it the way the manual says though. You can do it the "old fashoned" way. Pull # 1 plug and rotate the crank to bring it up to TDC. You can stick a dial indicator in the spark plug hole and find TDC that way. Then just compare to the indexing scale. You can also get close just by eye. A degree or 2 is no big deal.
