My poor Super Tigre .45. I used a Davis conversion head and Davis's fuel that was purchased as concentrate then cut 50/50 with Kerosene. The little thing sounded like a 3408 Cat on a cold morning. My patio looked like someone spilled waste oil from an engine getting it's first change at 12,000 hours... Then I read the instructions!

Luckily my engine survived undamaged. After about a quart of fuel (and some required reading) I am now very pleased. The residue is more like the color of fresh engine oil with an occasional black spot. It doesn't knock and transitions cleanly. It is turning a 12X6-10 Zinger just under 10,000 r.p.m. and idles effortlessly. One thought about the power output, on my thrust HP calculator the engine makes nearly the same static thrust with a 12x6 on Kerosene as with a 10X6 on glow. Although I am sure the program likely does not compensate for efficiency at lower R.P.M. etc. I still though it was an amusing statistic.

I don't appreciate the smell of Kerosene and could not find a direct answer searching this forum but is it OK to substitute #2 diesel for the Kerosene? Also why is Kerosene preferred over diesel when the diesel has better lubrication qualities?

Thanks in advance and take care, Cliff
