This is interesting... everything works as it should. Well, at least, everything is moving.... used the naval literature and still is doing the same thing... at least the 5SPI is perfect... I can’t figure it out.. I keep wondering if the connecting rod is out or if the PO rotated the eccentric cam somehow. I don’t even know if that’s possible.... oh also, timing is spot on thanks! Hmmm ,Yetibelle, looking at the eccentric again, I wonder if the spring tension has worn , or maybe too tight....time to play.. I’ll report back to see if I get any changes playing with spring pressure....
