Well to start with mop made the offer for him to keep it. I think a fair resolution to both parties would be to SELL the carb and split the money. Obviuosly mop sees something wrong in his dealings (intentional or not) and made an offer to rectify the situation. if you think that is not a fair offer then you should tell mop "that was a stupid thing to do". Maybe jrlj values his time more than you do and feels like this is fair. you fellas act as if jrlj is stealing his carb when that is in no way the case. I assume mop is a grown man that can make decisions on his own whether good or bad he still made it. in short, live with the decision you made.. good or bad.
I hope I didnt ruffle too many feathers. its just my .02.
