Hi,

I have one of these engines in my buggy 1/8 scale.Runs great.Has about a gallon and one half through it.Ive never timed it but seems like I put fuel in it quite a bit.Thinking about racing it soon.So what temps do you guys run for best power and fuel usage.I have the idle and HSN leaned quite a bit.Your thoughts please.

Thank You

Im running the JP-3 pipe with the big restrictor.Seems like no matter what it runs clean not fat.Until I come out of the corner for the long straight,and then its fat for 2 sec or so and cleans up.I run around 220-240 temp 30% Byrons.Any thoughts?

Thanks
