mariner 2hp 1981

[trout4chris]

i have mariner 2hp 1981. not sure where to put the lever on the gas adjustment. do i have it open for trolling speed or closer to close, or in the middle? do i put it on open when at full throttle? also it doesnt want to stay anywhere above the start line at those higher speeds, it vibrates back down to idle speeds.<br /><br /><br /> http://img93.imageshack.us/img93/2238/gasadjustment8mc.jpg <br /><br /> http://img93.imageshack.us/img93/8647/marinerfront6xl.jpg <br /><br /> http://img86.imageshack.us/img86/2368/sideview5yj.jpg

The valve is meant to be open or closed. Open when in use, closed when done.

OK, just so we're clear, the first pic is the gas valve.<br /><br />The second pic and your second question relate to the throttle lever.<br /><br />I don't know what that lever and linkage look like under the shroud. Remove it and watch the linkage as you slide the lever through it's normal travel. Unless someone has more detailed knowledge of that particular model, you're going to have to see if you can spot some worn or missing bushing for example that is now allowing too much slop in the mechanism. You may just need to tighten up the pivot bolt/screw for that lever.
