Got a Yamaha 90hp 97 mod used a few years ago. It runs rough at low end
through mid range. Last two seasons I have taken it to a shop where the
mechanic soaks the carburators. Guy says that it is a mystery to him that
it keeps doing it and says he has never had one act quite like this
before. He has been out on a water test and says it sounds like it is
dropping one of the cylinders. I see on the Yamaha home site that there
are carburator repair kits available. Are there any Yamaha mechanics on
here that think a repair kit for each of the three carburators is going to
accomplish any more than soaking the carbs? Thanks for any advise. NV
