Inferno, thanks for the advise.
The gearing in my revo is stock, and Im using the plug that comes with the motor. Ive stepped down to Odonnels 20 % with this new motor. (only 20 has been run thru it so far.)
I played with it a little last night, and got the temp to come down on it, but Im running close to 5 turns out on the high speed needle.

I did notice that it was a little difficult to get fuel to flow thru it, I pulled the line off the muffler, and tried blowing thru it while trying to start it. Damn near mad myself dizzy trying to get fuel to flow. Any thoughts on that?
