I’ve found this on YouTube.
It is not directly WM20 related, but there are some cool slow-motion videos
Of a 4T Briggs & Stratton SV engine,
With a see-through head, so you can actually see every stroke as it happens.
Hope you enjoy…
:laughing: :laughing: :laughing: ....That guy needs to get out more...Very entertaining, though I'm not too sure it was very instructive... The oil was probably from the breather. It looks like you can conclude that the engine is well made and should last a while in standard form mounted to a lawnmower!....Ian
His videos have been around for a while.
The earlier ones were very interesting as he ran the engine on a variety of fuels and with the high speed camera, slowed down you got a really clear vision of the ignitions and progression of the flame front.
I had hoped he would do a series with varied valve timing and ignition timing.
Naturally the end point will be to run to destruction, but those SV briggs are way over engineered, rather like a certain motorcycle some of us might be familiar with.
a color tune does the same job which is why I keep rabbiting about them.
