I am brand new to THIS forum. I want to apologize to HONDADUDE for shooting him a private message. I was trying to learn this forum, and I PM'd him by mistake.

My father recently died, and he left me his 1999 BF40 on a pontoon boat. The motor probably as 25 hours (or less) on her. I transported the entire rig back to Florida late last year. Since the boat sat for a while, I removed the fuel. I rebuilt the three carbs on the motor. am still getting inconsistent Idle with this motor. sometimes it will be 850 RPMs then it would ump to 1500 for no warning..Back and forth.

Do we have any ideas what could b wrong
 
Carb's will most likely still be the issue. Their are passages and circuts that cannot be accesed. Their are instances when not even a sonic cleaner can help. If you want it to run correctly then replace the carbs. Thank's Martin
