How did/do you set the coil "gap" to the flywheel magnets? I thought you needed a special thing like a flywheel hole in the top to set the proper gap? Thanks.
@richardwernst You are correct, the coil "air gaps" do have to be properly set...If the coils are set "in" too far from the flywheel magnets and you will have weak/no spark. Set the coils too close to the flywheel, and the coils will rub/jam on the flywheel...There is an expensive tool for aligning the coils properly...BUT, usually they can be set close enough by lining up the coil laminations with the machined surfaces on the mag plate just below the coils, torque the flywheel also...D
Some advice: Always use a torque wrench to secure the flywheel nut to its specified rating. Yes, you can guesstimate, but why do that? You can purchase an inexpensive wrench from Sears. Also, buy a strap wrench to hold the flywheel so you can torque it properly. Your outlay for both should be under $30. Money well spent!
That good ol 10hp will be purring in no time...

You have the manual of this engine because he buys one and it did not bring manual.
