19hp Craftsman Twin Tune Up Specs Needed / Runs Poorly

What is the ignition coil gap to magneto supposed to be ?

I just replaced the coil because of a No-Start condition.
It was running great, I shut it off and backfired through carb then it wouldn't re-start a little while later.
Thought it was the carb. Then I discovered it had no spark.
The sparkplug wires were badly chaffed so I installed a new coil.
It runs now but it is very hard to start and runs like crap.
Not sure if its a weak spark or fuel condition so I'm checking the basics and the correct ignition coil air gap to magneto.
I measured the gap before removing the old one and came up with .006 so I set the new coil at .006 but not sure if that's correct.

 

On the engine itself, someplace, but most likely on the blower housing, you should find the engine make, model, type, or other such information, and that will point you in the right direction as far as getting the correct spec's.

 

Thanks for the reply. I did check there but it only displays the make, model and serial number.
I looked everywhere on the engine and tractor.
I bought it used so no owners manual

 

.010". I usually just use a business card out of my wallet.
