I have a Losi 8 T 3.0 with a Novarossi Roma .25 trugy engine. The engine has an 8mm Venturi, 9886/41001 nova pipe and short manifold combo. I also have 4 aluminum clutch shoes with stiff springs.

I have about 1 1/4 gallon of fuel through the motor and cant get a good tune. It keeps running hot - 260 - 290. Also I cant get a nice clean sound on the straightaway, it sounds rich or fat, but If I lean it out the engine runs too hot.

Is it normal for the roma to run hot? Do I need to break it in more?
Is there a chance that I have the wrong pipe/manifold pipe combo? The combo I have I pulled off this forum, but when I look on NR website neither option is recommended for this motor?

Any recommendations or info on your experience with roma's will be a huge help
