Kawasaki FH580V timing issue

This engine is from a John Deere GT235. It is a Kawasaki FH580V, 2-cyl, 4stroke. I picked it up from a yard sale.  When I got it, it was running on 1 cylinder. I checked compression and one of the cylinders was at 0 psi.  I removed the engine, split the case and found that the ring gaps had aligned. I reoriented the rings according to the tech manual. Reinstalled the pistons, crank and camshafts. I aligned the crank and cam shafts using the timing mars. Reinstalled everything, but when I go to start the engine I see gas spewing out of the carb. I have taken this engine apart 3 times to insure the timing marks are ok and they are. Here are my questions:
1. which cylinder is #1 looking down at the flywheel?
2. When aligning the the crank and cam shafts is cyl #1 completely up in the cylinder or down?
 
Thanks

Just found this (on-line):
 
Cylinder #1 is Closest to the Flywheel on Fuel Pump Side 

Will it continue to run spraying some starting/carb cleaner down the throttle bore?.
 
Do you have a fuel pump on the machine?
 
If yes to both, pull the fuel line to the carb, crank over the machine with the fuel line going into a container to catch it.  You should see fuel pumping out into it (Just cranking , not just running).
 
Also, loosen the gas cap (should it be clogged) and see if there's any difference.

Pull the valve covers And engine cover and then check the timing.
 
You want to check that the pistons at TDC, intake cam just opened and closed (compression stroke) and ignition coil lines up with the flywheel magnet
 
Sounds like one of those is not in sync.. (intake cam OPEN when the piston is coming up, -pushing air OUT OF THE intake/manifold..
 
.
.

Does the stock cam have and plastic parts attached to it?
 
It does sound as if the lobe(s) are in-correct.
 
You may want to look up a new cam and compare to yours.. .

Tried to paste an excel spreadsheet into the last post. Did not work. I'll try again to post.

No I have not.
I ordered a new camshaft. When I compared it to the existing camshaft it is exactly the same as a new one.
 
If I could send a pic I could show the alignment of the crank and cam shafts.
 
The only other part that could be misaligned is the mating gear to the camshaft located on the crankshaft. This gear looks like it is pressed on. So in my simple mind it is possible for this gear to shift.
 
I keep going back to when I first rebuilt the engine. It started and ran for about 45-60 seconds then it quit. That's when I noticed the gas coming out of the carb. That's when i realized the mechanical timing was not correct.
 
I am going to order a new crankshaft and compare to existing one.
 

That secondary gear on the crank should come off easily.  
 
I just replaced that gear on a Briggs PW in which the alignment pin sheared off.
The new gear was now steel, not plastic...
 
.

After installing the new crankshaft, the engine started immediately and ran for about 30-45 seconds and then it quit. I checked compression and cyl #2 had only 30psi. I pulled the engine and again the crankshaft gear has rotated out of position from the keyway. Something is binding causing the gear to slip.
 
Any suggestions? piston/rings? Help would be appreciated.

Yes
