hi guys. I just purchased the warhead evo 2 days ago.its on the way to me now. I hear mixed reviews about it but like one guy said ..how often do you hear someone make posts about positive stuff? they only post for the most part when pissed or needing hlep with repairs.. so of course it seems negative. anyhow.. i have seen a quite a bit of posting about run temps.. my tsunami ran at 225-250 with a .18 engine(this was my first nitro). and i have been told that an engine head should never read over 260-270 very max or your cookin motor. but i am hearing people (including hobby shop people) say 300 is good running temp for the evo?? I would like several more opinions on this matter..no newbie answer please..experienced evo owner answers only. and also, should it be a different temp during breakin? one more question. its my understanding that you keep your idle screw hole at about a 3 millimeter opening.so, why would it matter how much air an air filter can collect if only so much can go threw the carb anyway?asking this cause I was thinkin of getting a k&n air filter which says it increases air flow by 50-200 percent. what good is that if flow is restriced inside carb?doesn't too much air kill engine?? thanks for responses in advance guys..much appreciated.
