Andy, are you saying it was 5 deg below F. not C.?? Wow, what happend to fall?? I'm not going to tell you the temps here

I can imagine if it was that cold that the biodiesel would be pretty viscous and not want to vaporize. You blocked the cooling fins but the crankcase was prabably really cold still so that wouldn't help vaporizatdddion.


I got my .061 PAW to run about 4,400 to 11,400 rpm on a 7x4 MAS. It would max out at 12K fully leaned but that didn't produce the best running.

Any body know the thrust of a 7x4 at 11K?
