is the gasket supposed to fit inside the decomp hole and then the screw with the copper washer holds the plug in where the lathed part of the plug is? right? how to u get the plug in. it seems like the gasket is too big? any tricks? also how do u tighten up the cam chain tensioner? i read in the manual what to do, but mine doesn't move a milimeter. could it be stuck? how do u loosen it? lastly, what's the word on the dr.d wet sump conversion for an 02 426? good, bad, not worth it? anyone use it? thanks for all your help!
