9.9 won't start no spark

No, did the old pulled spark plug against a bolt.

Was the bolt a bare metal bolt? Outboard blocks and head bolts can be painted with pretty thick anti-corrosion coatings that can block current to ground a plug touched to them. Run a jumper cable from the (-) terminal of the battery back and clip the firing end of the plug in see if it sparks when cranked... That is 100% certain ground. Can also stick your finger in the plug boot and crank... If you jump more than 6" off the ground like you touched an electric fence I'd say you have spark :).
