You need the factory manual before you start doing any more parts changing. Sounds like a float setting problem to me. If anyone tells you the float needs to be level, go buy a factory manual. $20 on ebay and worth way more.

Idle issues can range from low idle timing to dried fuel clogging the special dedicated idle passages in the upper carb body. Alway possible you may need to pull the carbs apart and overhaul them. Agree with wired247, if you want to get into the details of servicing your engine yourself-get a factory service manual. That is only reference manual to use on that engine. You can get a factory original from the original printer: outboardbooks.com.
