I would check to see if the stock numbers and the HMF numbers are the same. I think that some jets do not always mean the same by code. Try to find a cross reference or call HMF to be sure. But yeah the black smoke is raw fuel. I just opened up my exhaust and I get the same thing and you can smell the fuel when its cold or when you get it in a bind.

The stock big bear jet is not a 135. Its like a 112 or 114. You def. need to rejet it.

Yep, IIRC the stocker is like a 112.5 or something like that, im running a 125 main now witht he snorkel and HMF. SOmebody must have put a 135 in yours becuase thats wayyy too rich.
