I have fixed up several old motors through the years. I have used this site for two carburetor kits not on an old mercury 9.8 and an old evinrude fisherman. The evinrude ride kit had a float that was not compatible despite the matching numbers and recommendation. I just ordered one for my mercury by calling giving e serial number and numbers off the carb. It came and the only parts that were right were the seals. The needle was wrong the lean screw was two inches short despite the picture and there were four screws I assume where for the fuel pump body but were also not the right size. They were very helpful both times and mean well but this type of quality in kits is terrible.
