I just got back from the Silver State race and ran two 367's in my 8ight and 8ight T. I spent the better part of practice and the heats trying to get them to run right. My bad for not making sure they were broke in right before I left home. These are my first two Rossi's and the tuning can be a bit of a headache. I think I ended up with a 6TGC in the buggy and 5TGC in the truggy for the mains. Temps were around 220 to 245 on both and once I found the plug that worked no flame outs and the powerband was good all the way through. It was a clay track and throttle control was a must to keep a set of tires from wearing out too quick. Best motors I have run (owned or barrowed), though neither were stock as I like my motors modded out.
