Yeah the burning smell is something that I never experienced. A burnt clutch is a acrid smell that is immediately recognizable. Granted the MC is a plastic POS but I don't believe you you could smell it, the problem typically is with the internal seals. Then again never say never right? There have been times when I have smelled something that has worried me only to find that it was coming from another vehicle just making it into the cabin a minute later. Anyways, good luck and report back what you find so it can help others. Have a great weekend!
