Flywheel removal on Briggs & Stratton engines

The following applies to most B&S engines with the square starter shaft. This procedure will be needed to gain access to the points and condenser (on engines without electronic ignition), oil seal, etc.

(From: Foxeye (foxeye@www.compumise.com).)

The square shaft which turns one direction but not the other is the recoil starter pawl. This can be pulled straight up from the round cup that it sits in. There should be a couple of steel balls inside. Some models have a large internal snap ring that holds this in the cup. Remove ring, and pull it straight up. Use a magnet to remove the steel balls. Once you have this starter pawl removed, and the steel balls, hold the flywheel, stationary, and using a block of wood, bump one of the lugs on the outside of the starter cup in a CCW direction.

Once you break it free of its torque, it should be able to be spun off CCW. Remove this starter cup, and the beveled bellville washer under it. Now your ready for your flywheel puller. A strap wrench can also be used to turn this starter cup loose. When installing the starter cup, make sure it is clean and free of grease and oils. A drop of oil or a light coating of grease on the crankshafts stub end (over which the starter pawl goes) is usually recommended. The starter cup only needs to be snugged down, and you don't have to go overboard trying to torque it to ungodly tightness. Snug is sufficient.

Drop in the starter pawl, into the cup over the stub of the crank, and drop in the steel balls, replace larger flat cover over this assy, and insert snap ring if there was one.
