RE: Official HPI MT2 Thread
weird its only 70% on. I got a T-15 in mine and it fully flush with the gear. Sounds like you might be missing part of the clutch I think there is a washer thats supposed to be in it that should probably push it out like 1mm or 2 (or the guy had the wrong clutch bell on it). Personally I'd take the clutch apart and follow the pic I attached (the pics off the MT1 but its pretty much the same exact setup)
