I had posted a two-part question the other day...one part was answered, but no one answered the second part. I inadvertantly moved the lever that is on the opposite side of my gear shifter...it is near the gas plug in thingy. What is the purpose of this knob, and what did moving it do, or what will it affect. My next time out is on vacation, and I want to make sure my motor will run.<br /><br />Thanks.
