Starting a "small Engine"?

I have this old engine that in my opinion i should be able to start if i get it going fast enough, but thats the problem, i have no way to get that initial rotation needed to start the engine. the engine originally had an electric start but the motor is fried and i don't want to spend $100+ on a replacement. Another problem is that it is a 15 hp engine that is difficult to turn past the point were the spark goes off with any speed at all. Any suggestions (even ones that are out there)?

Buy a used starter on ebay for $20.

I am assuming that you have verified that fuel is getting to the combustion cylinder? You have compression? And you have spark delivered at the correct time?, then it should start with a little effort. Without all of those 3 things (plus air) it won't start no matter how fast you can spin it over. Is there a recoil starter available for your motor?

I believe from previous posts that engine is a Briggs engine, isn't it? That likely has a compression release on the exhaust valve that may help. Try setting the valve tappet clearances. That may get you the spin you need just with the pull rope.

I understood this as the OP has no recoil starter. If there is a recoil starter on the unit and you still can't start it, try the valve adjustment.

I may have missed a couple beats somewhere, but I thought this was a rebuild of an old garden tractor with the starter gone and he had come up with a recoil starter to retro fit it.
