Jim, sorry I missed your initial post [thanks John T.]. ~I have been working on my home network & after some system cleaning all the posts show up as not read, so I seem to not know where I am right now. ~Jim, look closely for that mark. It is really hard to find at times [both the cam & crank marks should be on the pulley side of the gears. ~If you can't find the mark(s) then a good place to start is install the flywheel & turn the flywheel so the "L/H ex open" is in line with the case mark, then install the cam so the L/H exhaust lobe of the cam is just starting to lift [or move] the L/H exhaust lifter. You want it to just barely start to move the lifter [about .015"-.020"]. Then [if the head is still off] install a long wire [I use a tig welding rod or coat hanger wire]from a dial indicator mounted on the front of the block to the L/H exhaust lifter & "0" it with the lifter on the cam base circle, then turn the flywheel until you see .020" on the indicator, if it is timed correctly the "L/H ex open" on the flywheel should be within 1" of the case mark. ~When the head is on & the valve train is in & adjusted [use .020" cold on the L/H exhaust only] turn the flywheel again until the valve lash just comes out of the L/H exhaust rocker & at that time the "L/H ex open" should still be within 1" of the case mark. Then re-set the L/H exhaust valve to .022" as well as the others, then re-set all to .020" when hot.

As with many things there are often several right answers and a few wrong ones. Some purist I'm sure will disagree to no end with what I will tell you but most of us out here in the real world don't really care do we ? Some of them only bring their noses down out of the air long enough to look down them anyway. If you are like me you are only doing this old tractor stuff because you enjoy it. You
