Briggs & Stratton small engines, often used in lawn mowers, rototillers and snow blowers, have an ignition system that operates off of the flywheel. Magnets in the side of the flywheel rotate past the ignition coil, signaling the coil to send an electrical charge to the spark plug to fire the engine. The engine flywheel must be removed if it is damaged and requires replacement, but also if you need to access the ignition parts and components. Most of the task can be completed with a basic socket wrench set, but you'll need a specialized flywheel puller tool.
Locate the two holes on top of the flywheel that are directly in-line with each other on each side of the crankshaft. Line up the holes in the flywheel puller tool with the holes in the top of the flywheel. Slide a bolt into each hole of the flywheel puller tool. Screw the bolts into the holes on top of the flywheel that are on each side of the crankshaft.
Unscrew the flywheel retaining nut with a socket wrench while holding the flywheel with a strap wrench to prevent the flywheel from moving. Pull the metal cup from the engine crankshaft. Thread the flywheel retaining nut onto the last few crankshaft threads by hand to protect the threads when using a flywheel removal tool. [links]
Yet this spec is also found in the '45 manual, long before rubber bushings were used, w/no mention of "backing off 2 cotter pin slots". [links]
The later manuals ('53 & '65) say to use this spec for rubber-bushed spring pivots. For bronze bushed pivots, the say to "tighten the retaining nut, after which back it off 2 cotter pin slots", then "be sure the nut is drawn up tight, however, it must be sufficiently loose to allow the spring to pivot freely".

They are broken down by Willys Group number, corresponding to the sections of the parts lists that you'll find the fasteners in.
1) There is a MAJOR discrepancy between earlier and later manuals here, and I don't know what to make of it. There's 3 possibilities:
They are for information only. I make no representation as to which of the differing specs is correct. That's up to you.
These bolts are 1/2"-13, and are almost certainly capable of far more than 38-42 lbs. For instance, the crankshaft bearing cap bolts are also 1/2"- 13, but get 65-75 lbs. torque.
