I have a 96 Johnson 200 Venom and was hoping for a quick fix. I need to adjust the idle on the motor and not real sure do I need to do this on the carbs or is the an idle arm adjustment I can make. I am idleing around 800 rpms and I would like to move it up to 900 or just a like more the engine is wanting to die but if I give it just a little throttle it will run smooth. Thanks Brian
