    New Carb for Honda BF90 has no idle mixture adjustment?

    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...

    2004 Johnson 4-stroke fuel injected driving me nuts!!

    Rides fine for a little while but then begins to surge at 3/4- full throttle. Pull back to neutral for a few seconds then takes off like a rocket for 20-30 seconds then repeat! I have cleaned fuel tank, replaced all lines and replace vst with new high pressure fuel pump. I know I need a fuel...

    2004 Johnson 4-stroke fuel injected surging problem

    I have a 2004 Johnson 90hp 4-stroke fuel injected engine on a 22 ft. pontoon. It has sat for 3 years straight and I have been going though it. 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...
