GIF anim worked great! That is really helpful man. Thank you!
Those things look like what we put in 2-strokes in the '60s and '70s. They made for great engine braking. I think what put them out of style is that they sucked in as much dirt as they blew out air!They worked like jake brakes on diesel trucks and they really slow you down without locking up the wheel.Bare
That's inneresting - please 'splain in a little more detail. I unnerstand how decompressors work, I unnerstand engine braking, I unnerstand engines. I just don't get how this works. How do you get compression braking with a decompressor? I'm sure it will all be clear as mud if you just clue me in to what I'm missing.
But while it's sucking in that new air, it also sucks dirt!
maybe that's what that mystery hole was inside the exhaust port.
