I was understanding you did NOT have spark..

If you have spark now...
If the engine turns over...
The mower should start with a very small shot of starting fluid...with choke open
It may die right a way...but it should start...

Will it?

No sir even with starter fluid no attempt to fire the only thing that happens is after cranking for quite a bit a small backfire. I am by no means an expert on small engines but I'm a pretty good troubleshooter and I am totally stumped

No mention of checking the valves after pulling the heads off

I had only pulled one head. I did go back and check/adjust the rockers on both and rotating the engine the valves seem to be working correctly

IF .... you have fuel... and spark ...... it has to be timing, that's all an engine requires, it should at least attempt to run.

Oil breather & intake MANIFOLD not blocked, ?? muffler not blocked ?? ...

If all your info is correct and the things you did are correct and with all the comments made and you say you already did that and you have this and you have that I would have to say there is one thing compression. If you say you have that my next post will be there no fix other than a new engine

Oil breather is the only thing uncheck, it's under the flywheel

I do not have a compression tester to get an accurate reading but loss of compression on both I would think unlikely. The one cylinder and head were not touched during this repair.

You set the valve clearance correctly at TDC on that cylinder?

Yes tdc judged buy valve movements, confirmed with a wooden rod in the plug socket

Well I hate to say this but if you took the cam out you had to touch the other head at some time if not your lifters would be still in the block and your rods are too. You had to adjust the valves if you pulled the cam out if not then how did you get the rods back in and if not then how did you adjust the valves. Seems to be going in a circle about your problems your having with the engine. Just trying to clear things up a bit and what you a missing on getting your engine running.how about what you set your valves at? Starter fluid as in lighter fluid for grills or something more????? Try some either and see what happens
