Oscar,

I am running 15% fuel from my local hobby store with no additives. I may not be a lot of excess, it is my first 4 stroke. It just seems messy, I did bend a tube and vent the oil out of the bottom of my plane. I called and spoke with Pete the guy who makes the engines in England and he explained how to go about it. Maybe I will get one more and put them on this OV-10, I thought gassers would be easier, more cost effective, and less messy.

Thank for the advice,

Paul
