does this sound like its running rich?

I am thinking about this, it must be those drilled out pilots. A 48 pilot jet has an opening of .48mm, correspondingly. a 45 pilot jet has an opening of .45mm. Unless your buddy has a machine shop with micro precision equipment, I would bet that those drilled jets are WAY too large - hense a rich condition down low. This may not show up on a plug reading, which IMHO are useless anyway.
It is also possible that you have some clogged passageways elsewhere in those carbs. Clean them up real good and go back to stock settings so you can properly diagnose the problem. There are too many variables now. JB

Are you saying that your engine temp does not get past 104 C (celsius)? That would be 219 F which is about right. Just checking.

thanks for the pics, ill print those out and the instructions and when the carbs come off ill make sure the tubes are on the correct carbs. hopefully the next time we get in there we can resolve the issues
thanks for the info and help guys. ill keep you posted as we make progress

Wow that's confusing. Haha. I know that temp and atmospheric pressure have a profound effect on vacuum snd carb operation, but if I tried to explain how, I'd be taking a shot in the dark.
