Those of you that are looking to buy or have your carburator's rebuilt or need injectors here is a site that might help. We used this site when my friend kicked the stud off of the carb that holds the flame arrestor on his Rinker 290. Merc wanted $900 for the carb. This company rebuilt it and it has a lifetime warrenty all for around $175.
