We are working on a Tecumeseh HH80 that is in a little Massey Ferguson 8 Hydro. I had finally gave in an removed the head to check that the crank and cam were at least close to where they needed to be without tearing it further apart.
I have the flywheel off and for lack of the correct name, stator assembly maybe? The bolt holes are slotted. I checked to see when the points would open when the piston was near TDC. They don't open until after TDC and the piston is already 3/8" down the bore. To me this doesn't seem right. The points are operated from the lobe on the crank. Should the points be breaking before TDC or is breaking after TDC correct?
