Briggs &Stratton 287707

I have a Briggs model 287707, Type 0227 01, Code 9410 1046.
bought on ebay. Motor would turn just a little and stop hooked jumpers to battery got to turn over but backfired every stroke. Suspected timing key in fly because of a little shear mark. I replaced now I can get motor to run on ilde but sounds like timing is off because when I throttle up it will backfire and quit. When idling motor sounds like it is laboring, very loud exhaust. how do I set the timing? I have checked air gap on the coil also the engine doesn't look like it has been apart so I am thinking no one has tampered with timing inside. This engine has overhead valves. Anyone know where I can get a manual for this one.
Thanks for looking Steve.

You need to pull off the valve/rocker arm cover, your problem
is likely there. Unless you didn't torque the flywheel nut
enough, and sheared the new key.

I pulled the cover off and everything looks fine. The coil seems to be off for the timing position with the mag. The alignment is off and I can't see it. A manual would be cool.

There is no adjustment of the coil, it sounds like the new key is
sheared.
