Briggs & Stratton Engines

Briggs and Stratton was established early this century in the USA, and to this day, they still produce stationary and lawn mower engines.

I have had about 30 newer models of Briggs & Stratton lawn mowers over the last few years, but very few old stationary engines were ever brought to Australia. Therefore, although being a very common engine in the USA, my Briggs & Stratton WMB engine is considered to be a rare find. The WM is thought to stand for Washing Machine, and some of these engines were used on Maytag washing machines after Maytag ceased production of their own engines.

Mine is connected to a Lucas 14AC car alternator, made in England. It has a regulator, ammeter and indicator light built into the unit.

When I found the engine, it was missing the cowling, flywheel, points cover, flywheel key, governor vane and linkages, and the original oil bath carburettor had been replaced with a paper element filter. I have now obtained all the missing parts, and it is now operational. It will start second pull every time, once with the choke, then away she goes. I have repainted it in a gloss black finish, which although it is not the original colour, still looks good. The big end is less than perfect, but it still runs fine, quite quietly.

I had been having trouble with the alternator not generating any power, possibly due to either the alternator, regulator or both being faulty, so after much fiddling I replaced the 50's model Lucas 14AC alternator with an 80's version of the same model, also a 14AC. The difference lies only in the fact that the new one has a regulator built in the back of the unit. This means that I can kill two birds with one stone, and a little bit of dummy wiring to the old regulator, and you would never know!

I have restored the alternator also.
