I have a 2003 BF90. The main #4 carb got damaged/cracked while I was cleaning it. (Don't ask). $285 later and I have a new shiny one now. However, the new carb's idle mixture screw is limited. The screw has ears on it to only allow it to be turned a quarter turn each way. Is this something new...

All new maintenance parts installed and had to clean out the fuel tank as well. Took it on the lake today and ran it. Takes off like a rocket and runs at...
