[QUOTE=CE Mississippi] Double checked wires . All good . Timing ok . Now checking valve adjustment. A little confused.

On the D-17 number 1 and 4 are TDC at same ]
They are both up on TOP center but not TDC and the camshaft turns half speed of crank so the valve lash is adjustable on different valves in different positions. Not confusing when you understand how it works.

 TDC is Top Dead Center no matter what stroke it's on. A 4 stroke engine has TDC on the compression stroke, AND TDC of the exhaust stoke. Cylinder one and cylinder four are both at TDC at the same time, BUT, one is on compression and the other is on exhaust.

Most, if not all "shuttle clutches" were on the left side of the tractor. A shuttle clutch gives you forward or reverse, without shifting gears.
 The "power director" is on the right side, and gives you 2 forward speeds in the same gear.
