[SEL] Briggs Question

[Bill Brueck]

I don't know which models this pertains to, or even if Briggs had this
feature, but some small engines had a compression release to make them
easier to crank.  There was a second action on the cam that held the exhaust
valve open just a little to accomplish this.  As soon as the engine had a
little speed up the little mechanism on the camshaft would swing out of the
way to give the engine full compression.

See if the exhaust valve closes all the way when you hold the engine upside
down.  I think the compression release would not engage if the engine was
upside down.

It's been a 30+ years since I used to work on these for a living.  I
remember running across this feature and thinking it was kind of silly on
such a small engine.  I can picture the cam action in my mind...sort of.

Maybe someone can be more specific.
