Dan,
Synchronizing two carbs is a tricky process and the exact steps for your engine can be found in a shop manual. Here is one online you may want to check out: Yamaha Outboard Shop Manual 90 HP You may also be able to find these shop manuals at your local library. Also, if you have never calibrated dual carbs before you may want to bring it into a good shop and have it done. |

I find that even as a mechanic it is worth the time and money to send them in for calibration,so far it sounds like you are going in the right direction,I posted about a 130 hp ,read the thread,the secret seems to be cleaning,also make SURE your fuel and filters are clean,if you have a screen filter in line ,be sure to change it,these carbs are VERY suseptable to dirt,it seems the slightest bit bit,and your sunk!
