Did anyone ahve a problem with there engine staying tuned. It seems no matter what I do the engine runs lean and hot. Did any one have a problem with the carb or is it just me?

I have even shimmed the motor (0.2mm shim) but still I can't get the motor to perform unless it is around 260 to 270 degrees. I was thinking about changing the carb to the trusty Novarossi MT12 on like I did with my older Sirio motors. It fixed those and they run strong at my local club tracks.

Changing to the Nova carb makes it much easier to tune. The stock carb is overly sensitive.

I contacted the Tech Department at RD, and they told me to send the motor back to them. In which case they'll either repair it or replace it. I just want it to run right what ever the end result.

What temp are you guys running your engines at? I've been getting some really good run times with the engine running at about 235-240. Is that the range that you guys are at?
