This is a Breisch Olds engine built from a kit. Has good compression, runs very smoothly. I built a simpler mixing valve I found on a website. It’s tricky getting the right combination between the air and needle valve, but it works. I have the original mixing valve blank and all the drawings Has a 12 volt ignition coil and a anti siphon valve in tank.
