I have a 413 that I rebuilt and what some input as to the first start up and cam run it time. I have what RPMs the cam says it needs. Do I take out the spark plugs and turn it over to build oil pressure? And added to that my pressure gauge did not work, so can I tell if something is wrong before it locks up? _______________________________________________ Join Excite! - http://www.excite.com The most personalized portal on the Web!
