Simple diesel homebrew
Guys,
Has anyone used a simple diesel homebrew of Starter Fluid and SAE 20 wt motor oil? I know the John Deer SF works with a conventional ether/kero/oil but it seems that with other starting fluids with less ether more heptane you could just mix them with 25% mineral oil (need this to calm down the ether, castor won't work). I think you still need a SF that has ether listed as the first ingredient (this would indicate it had more ether than the next listed ingredient like heptane). In this mix the heptane replaces the kero. The important thing with this is to use mineral oil. The mineral oil calms the burn rate of the ether so it doesn't detonate. The mineral oil trick was an old Drone diesel method to get the 75/25 ether/oil mix to run in the fixed compression engines. Seems this simple mix should work for most sport flying.
Best, DennisT
