Thanks for the carb info that will really help.I got to fly the road runner again today and it ran great.I did some work on the throttle. I replaced the linkage on the bell crank and that made it a lot more stable and I now have A full throttle.I noticed at full throttle it had A little putting noisy? I guess that would mean it is to rich? and that I would have to open up the high speed needle A bit more?
Thanks Harold
