Lets not forget this outlived the engineers, workers, and owners of Briggs and Stratton engine company. Nice work fella too.

Homer Shaw of Galesburg, Kansas built 2 wheel garden tractors in the 1930's using this model engine. I had found one at a yard sale in the 1970's and ran it for plowing my garden through the 70's and 80's. The tractor had two steel wheels with spikes for traction, a 10" plow and a sickle bar mower. Steering was accomplished by individual brakes on the two wheels. The transmission was as used in automobiles with three speeds forward and on reverse. The reverse was a wonderful thing as, befor, had a David Bradley (Sears) with no reverse and if you I came too close to the fence at the end of the garden I had to wrestle it out and it was HEAVY. The Shaw could simply back up and be ready to go. I do remember that it was best to leave the engine idling as I went to lunch as if I didn't it was hard to start although it started easily for the first time in the morning. Thank you showing your Briggs. Oh, Mr. Shaw called his tractor the Shaw Do-All.

When I was 12 I need a air compressor I took a Briggs 1 1/2 hp engine and cut the camshaft in to and brazed the cam lobes 180 degrees apart. Then removed the carb and muffler and made a check valve with a spark plug, ball bearing and a spring. The engine would suck through intake and the exhaust and exit through the spark plug check valve like magic I had an air compressor 90 lb output

I bought a Chinese generator from Aldi. It ran for 10 minutes while I gave it an Initial load test. It never started again. I went to get it repaired under warranty and they had no options at all after considerable pretending that they did. In the finish they refunded my money and probably dumped it. Life cycle 10 minutes! I’m sure I could have fixed it and voided my warranty. The whole process was insane and sad that the choice was just dump the dud ones. I try to avoid Chinese crap these days.

Thanks Mike for taking the time to perform the detailed test, very interesting. Based on the bore and stroke, 8.95 cubic inches should yield a max torque of 5 - 6 foot-pounds, assuming the compression ratio is around 4.5:1. I think Briggs and Stratton used to derate their engines more back in the 1940's. In 1968 I remember looking at a Sears catalog from the 1940's and the rated engine horsepower was about half what similar sized engines in the late 1960's were rated. It's hard to beat cast iron for a rugged engine material.

I have worked as a small engine mechanic for the better part of 20 years now, and I'll be honest the best longest running engine across the board are these old cast iron engines. They always out last and out proformer over hours of service then the newer aluminum engines. While the Aluminum engines definitely will out perform in HP and RPMS they just don't beat there cast iron predecessors in over all long jevity and run hours. Anther case of quicker doesn't always last longer.

They built these small engines back then to LAST! Even though there are some good small engines available today they would not have the longevity of those old cast iron donks, they really are throw away these days, reasonably reliable but not worth rebuilding after X amount of hours or work, l have a few original old engines that run beautifully that are quite elderly, engines like the Villiers, Ronaldson Tippet ( built here in Australia) and l reckon the best & most reliable small engine from Honda is the “G” series side valve units from the 80’s they last forever but that’s my opinion based on the range of machines from pumps to generators that they were installed on when l ran a few equipment rental companies a few years back now, that was a good interesting test that you did as all your subject matter is great viewing, cheers for your efforts.👍

I have one of those. They are real workhorses. Unless you took yours apart, here are a few interesting pieces of trivia. This flathead (no overhead valves in the head) is relatively unique as the spark plug on the side does not screw into the combustion chamber, but screws into a small side pre combustion chamber with a small passage between the plug and chamber. The head is unique as the head fins are channels through the head for a smooth top on the engine without exposed top fins or a tin cover. The engine contains a real weight driven governor inside, and not a wind vane as is common on lawn mowers. Last time I fired mine up, it ran fine. The crankcase base is cast iron, and is oversize compared to modern engines. I have kept mine since I got it in high school due to the very unique design features.

The RF interference was a very common problem with the points and condenser ignition and the radio. In my 62 Falcon I bought a set of solid copper core plug wires with red clear outer rubber and the noise in the radio was uncontrollable. I even used the frequency filters on the plugs. Radio frequency interference and electronic devices of the analogue era and even today with sound equipment, wireless devices with musical or audio systems require sophisticated frequency filters to reduce that interference. I remember driving around with the popping sound of the spark plugs in the radio. Those were the days. Lol Thanks for the video. Maybe try doing an all analogue version with a mechanical scale, timing light, and ocyliscop old school style to show just how far technology has really come.
