ONAN P220 on 520H won't start

Well, I put the washers on the flywheel side of the engine and that seems to be working better as far as the starter to flywheel, but the engine won't start. I have a new coil, condenser, plug wires, plugs (not sure about the correct gap though), and a new electric fuel pump with filter. The mower ran one time and mowed the yard a month ago but has not started since then. It started one the first crank when I put all that in new. Is it possible the coil has failed? I even put the old plugs back in to see if that was the issue. The were not burnt. What should I check to test possible failures of the coil or fuel? I think the fuel is going to the carb but not sure if this is enough pressure? Not ready to give up yet...

I used a Match Book to set air gap

Also if the Magnets are rusty it wont create a spark

They say that the carb gums up fast on a onan, remove the fuel line at carb and crank engine, if you have fuel the carb float may be stuck

      WASHING PROVED DEADLY
      By Doodad
      Well, I guess I've gone too far this time. I've got what I believe to be a 1974 Wheel Horse C-120 (12 HP Kohler serial7326629) that has performed nicely so far but looked a bit dirty so I had the great idea of cleanin' her up a little. Washed the tractor but the engine was dirty and I thought it would be nice to clean that up too so I sprayed some orange citrus cleaner on it and hosed it off and boy it cleaned right up and looks great...the only problem is, now it won't start...just grinds when I key the switch. I'm getting ready to take the hood off and check for spark but I'm suspicioning it's probably sucked water into the carb when I tried to pull it into the shop after washing. Anyway, that's my starting point but, before I go to far, I wanted to see what the Wizards of Wrenches have to say about what's wrong. I did get it to backfire and consider that an improvement but, no-starty, me no smarty. From the Doodad

      1996 Wheel Horse 520H With 48 Inch Deck
      By lsc1257
      I have a 1996 520H Wheel Horse for sale.  The tractor has just over 800 hours on it.  It comes with a 48 inch deck.  The deck is a 1995 and has over 1,500 hours on it, as it came brand new with my 312-8 that I sold several years ago.  This 520-H has the swept front axle so it can handle a 60 inch deck.  I just replaced the battery and the deck belt this summer.  The engine is a 20HP Onan and it starts right up but requires the full choke.  The transmission is an Eaton 1100-062, hydrostatic.  The deck is in rough shape but the spindles appear to be in good working order.  The right rear tire has some cracking.  The original operator's manual for the 520H is included, as is the original operating and maintenance instructions for the deck, plus the installation instructions for the deck.  Also included is a new PTO belt and several miscellaneous deck wheels and rollers.  Additional pictures available upon request.  Asking $500.

      416 8 Onan / 312 Hydro with a 12 HP Kohler
      By odee61
      Will the PTO work from the 312 Hydro with a 12 hp Kohler onto the 416-8 Onan?  My PTO disc went today. Any help would be most appreciated.
