I have never seen my diesel get hot. If you lean it out too much it just quits. It is not like a glow engine in that regard - that is why I think Castor oil is a waste of money.

The fun thing about thease diesels is they will burn alot of different stuff so we can all have fun doing it our own way.

I've got about 20 more flying hours burning pump diesel and used oil (Black Brew) and it is working great for me. This stuff may be too messy for most people but it does run great. I haven't even been cleaning my plane. It looks like it has been in a forward combat aerodrome in WW1 for months[8D]

I will be trying it in a PAW .061 soon.

I love running this diesel. People always come up and ask about it, one guy called me "skywriter" due to the white contrail.

I fly for long time and when no one is around. I fly for 23 minuets ( 7 minuet reserve ) land and fill the tank through the fill port while the engine idles and take off again without ever shutting the engine off! Fuel cost is a non issue anymore!
