I am curious if anyone else has found the timing marks on a D-361 engine flywheel to be off by approx 10 degrees. I found this out when measuring piston protrusion above the deck. I had made a seperate pointer on front pulley before splitting tractor because it is hard to be real sure of the flywheel pointer as it is in the cluch housing after you split. When I turned engine to tdc mark piston was no all the way up, so I made my own tdc mark by the normal method of dialing up to stop, down .001 and back other way to down again .001 and then split the difference for true tdc. This of course means the timing at the pump is way off, almost 10 degrees early. Hard starting is the problem I am checking on, but owner claims it used to start fine. Hard to believe. History of engine it knocked rod out many years ago, reground crank, large end of rods have been machined once for sure and I think twice that is why I was checking piston protrusion. That is another story, but I was just curious if anyone has ever seen timing marks that far off and a possible explanation except flywheel marked wrong or dowels in crank wrong.
