WD timing problems

My Dad had his motor on the WD rebuilt. There don't appear to be any marks on the flywheel to time it up. Can't get it to fire. The valve cover is glued on pretty good so he doesn't want to take it off unless he has to. Where is TDC on the flywheel. Any pointers to getting it timed up right? Fuel is getting there, etc.
 
Take the number one spark plug out. Put your thumb of finger over the hole. Turn the engine until it blows your thumb off the hole. That is approx TDC for the engine. The mark should be within 4 inches of that event. Take the dist. cap off and pull the rotor and then the dust cover, replace the rotor. Loosen the distributor bolts so you can turn the body of the unit until the rotor is pointing opposit of the solinoid. Take off the rotor, replace dust cover. tighten bolts that hold the dist to hold it in place. Put the dist cap back on. Put your #1 spark wire over where the rotor is pointing to and then go in sequence from there. 1243. If you don't have a mark for TDC, you might still have a Fire or F mark. You need to have a timing light to time it from there. That should fine tune your rough adjustment.
 

Do you have a Magneto or Distributor..??

Still 6 Volt Pos. Ground..??

The Magneto may take a different approach to getting it to "Fire" at TDC...(Because of the Impulse Coupling)..

I would ask "Old" about timing your WD with a Magneto...
I have not timed one with a Mag in just too long to help you myself.
I am thinking that there is a "Lead amount of timing", to allow for the Impulse to load and trip at cranking RPM that is not necessary when using a Dist with Battery Ignition..
Do you hear the Mag impulse (Clanking) as you crank the engine..??
Was anything changed inside the Mag, during the rebuild.?

Ron..
 
do the spark plug thing, then look under the tractor, remove the flywheel cover and the TDC mark will be visible. You might want to put a wire in the spark plug hole, on top of the piston, and turn the engine until the piston is at the top. This should put the TDC mark in plain sight.Bob
