Nova Rossi Plus 4 .21ci (3.5cc) 2.5 gallons through mine and still running strong. I have had up to 13 minutes out of a tank in my MP9, 053 pipe works well for me on this also.
Idles very well also, had very limited flameouts with this motor also, still had the original glow plug in it unitl Friday (changed only for reliability purposes, plug was still working)
Just my experience with this motor.
