I think my engine is dying, it has about 9 gallons through it and it starting to show some red flags. It doesnt really hold a tune, constantly runs hot no matter how rich on hsn and lsn, isnt nearly as fast/preppy as it was a few months back, and constantly fouls glow plugs. I checked for air leaks and there was none. Any idea whats going on? Also, whats the best engine for the t maxx? Looking for something other than the traxxas engine to replace it with, if its dying. PM me if anyone has something for sale.
