"What made you fall in love with 4 stroke lawn mower motors? "
Simple for me, The mini bike that was attached to it
Because the lawn mower engine was the heart of the minibike, I had to learn how to keep the Heart alive and well.
Those lessons of how a 4cycle engine works have served me well in the 50 years since being introduced to minibikes.
Although I came to appreciate a Tecumseh, The Briggs is the superior engine in terms of simplicity and reliability.
Rods that withstand 5000 RPM all day long and for the most part, no junk float carbs.
When you shut off a Briggs the fuel stays in the tank not gumming up the carb unless it is the older ones with float carb and even those are better.
And Magnetron ignition!
