Hi again Beammeup, we seem to have posted simultaneously a few minutes ago - thanks Deejay, for pointing it out.

The nearest operators' manual that B&S have (yours is rather a late 80102)is here:

The nearest illustrated parts list is here:

(Deejay, as you can see, the spark plug shorting kill switch was normal for the 80102, and the 60102. That series of first-generation engines used a different governor design and had no provision for a kill switch contact on its base.)

Some other details: your engine was made on 15 August 1975. Since that is prior to 1983, it has breaker points, not breakerless ignition. The breaker points are in a little round tin box behind the flywheel. Your engine is 8 cubic inches displacement (130 cc), is the first design generation for that engine series, has a horizontal crankshaft and a Vacu-Jet carburetor, has plain main bearings, and has a rewind starter.
