[AT] TD6 Trackloader timing problems. Where is TDC

[Gene Dotson]

    Spencer;

    My method for finding TDC is to remove the spark plug and turn the 
engine till you have compression at upstroke. Turn till the valves on #4 are 
at the overlap position. This will put #1 at the firing position. Slowly 
rotate the crankshaft till you feel the relaxed spot as the piston crosses 
the top of its travel. This will give a true TDC on #1. Turn dtstrubutor 
backwards till the points just break.
    Rather than trying to start it on Gasoline, why not get it running on 
diesel and then switching to gasoline as you would when shutting down? Would 
save a lot of cranking. I would hesitate to use ether to start as this 
engine has a reputation for cracks.
