7117H hard starting

I ran it out of gas and now it won't start. You would think it's a diesel but a diesel is actually eaiser. I've tried dumping gas into carb but still no go. Any ideas? Thanks.

Jeff,
You just ran it dry running it or ran it dry and it's been sitting a while? Makes a difference. Anyway, assuming it's getting fuel to the carb, are you SURE that your fuel was fresh, clean and "DRY"? (NO water in it) Even a small amount of water can prevent the fuel from being drawn up the main jet. Fabricate a catch-pan from an aluminum food pan or plastic milk bottle such that it will slip in under the carb. (It's real tight on a KT.) While holding the fuel bowl on the carb, slightly loosen the bowl nut and drain the carb into the pan; both to prove fuel flow and to examine the fuel for contamination. You may have to ease the bowl loose from the gasket to get it to drain, but don't allow the gasket to get out of position. All that assumes a gravity-feed fuel system, which I think applies. If you have a fuel pump, you have to remove the fuel line from the carb, safely extend it as necessary to a catch-can, and crank the engine to prove the pump.
ALLOW ANY SPILL TO FULLY AIR DRY BEFORE ATTEMPTING A RESTART!
The only other likely thing is ignition. Does the engine have any history of hard starting? Even if not, remove the plugs, reconnect the coil wires to them and ground the plug bodies to engine metal. Crank the engine and observe for adequate spark. If none or doubtful, check/service/replace the points and condenser, by the book, and see what happens.
If you still have trouble, come on back and let us know. KT-17s are supposed to run!

Jeff, Two things I've done in the past is 1. Use starting fluid and 2. remove the spark plug and put a very small amount of gas in the spark plug hole. Be careful with this you don't want to wash the oil off the cylinder walls.

If this is a gravity (no fuel pump) carb it is easy to vapor lock the fuel line from the gas tank to the carb. Be very careful now! Have a container or something to catch the gas in. Disconnect the fuel line at the carb and when you get good flow out of the line quickly slide it back on the carb connection. On the B&S singles I have had to do this whenever I have removed the gas tank and reinstalled it.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul

      I assume it's a bosche, correct
