Wisconsin engine NH 66 baler questions

We have an old NH 66 baler with a Wisconsin engine on it. We were going to remove the engine, and get the clutch and parts to run it off the PTO. But, some folks wanted to borrow it and use it as a stationary baler. So, here we go trying to get it going.

The engine is a 2 cyl air cooled unit. We already had the magneto rebuilt, so it's in good shape. It was really hard to time the magneto when we put it back together - the timing mark on the drive gear (meshing with the magneto gear) was not obviously apparent at all. Should we be looking for a punched hole, a score mark, two punched holes on adjacent teeth, or what?

One of the intake valves is stuck. Anyone have any luck getting valves un-stuck without removing the head? I was thinking of soaking the area with penetrating oil, and gently tapping the valve closed, and letting the cam open it back up. Any other ideas?

The fuel line keeps loosing its prime - is the most likely culprit a leaky fuel line fitting? Is the fuel pump supposed to be able to prime the pump by that little hand lever? (it's a real pain!)

What's the best way to start these things - just keep turning the hand wheel?

Lastly, is it possible to mount the PTO clutch stuff on the flywheel, and be able to use the baler as either PTO-driven or engine-driven? Has anyone ever done that?

Thanks in advance...

There are two timing marks on the magneto teeth. The marks are on teeth that are probably 135 degrees apart, so it would appear that perhaps the gear was used on multiple magnetos and engines.

When are the plugs supposed to fire - when the pistons are at top dead center? If I time the magneto to the mark that I think is correct, the plugs fire at approximately 30 degrees after TDC, which I assume is incorrect (the mark on the other magneto tooth results in firing at around 150 degrees after TDC). I moved it a couple of teeth to get it to fire at TDC, but the engine still didn't have any life. It's not even firing with ether. Any ideas?

The valves are unstuck now - thanks for the advice.

The plugs are Champion D-16, and appear to have good spark. I can replace them tomorrow, but I doubt it'll make much difference.

One last thing - where can we get a carburetor rebuild kit? We have no idea what shape the carb is in, but it probably needs some attention. The local Ford New Holland dealer came up empty, except for a possible lead in Minnesota.

Thanks in advance, as always...

What's kind of scary is that these problems are all dealing with teh engine - we haven't even run a bale through the baler itself. We wanted to be able to run the thing off the engine so the Amish folks in our area could use it as a stationary baler. We would want to use it with the PTO, hence my questions re: being able to run it from either the engine or the PTO.

I'll change the spark plugs later today or tomorrow.

I took the carburetor off last night and cleaned it out real good. I imagine it's been rebuilt somewhat recently, as it didn't look too bad in there. The gasket even came off without any damage at all.

With the magneto timed to the mark correspoding to the keyway, the plugs fire at around 20-30 degrees after TDC. I don't know if that's where they should fire, but that's where things end up. I suppose it's possible that someone mis-timed the cam to the crankshaft, but the valves seem to be opening and closing at the proper time, at least by looking at the keyway for the belt pulley.

Is there an inspection plate that can be removed to check the cam/crank timing? If not, how difficult is it to remove the timing cover?

I'll need valve cover gaskets when I get this thing running - should I just make some out of gasket material?

Thanks much again.
