I was 2.5 t-maxx when or started to run like crap. The idle was low and was having a hard time keeping it from dieing. Tried to bump the idle up and I couldn't get it to change. Pulled the Fourier l filter off and found the throttle slide is all jacked up abs note closing and moving in its bore sideways. Is this a problem with these? I just ordered a 3.3 to replace the 2.5trx am I gunna have the same problem again or should I get a different carb?
