Greetings IMUL,

First off I guess I should say, that my altitude compensator is one of those round vacuum looking jobbies on top of the IP near the rear, and the adjusting screw is in plain sight on top of the unit, with a locking nut holding it in place. I'm not sure what the first reply post was talking about as far as having to disassemble or cut anything, just not the case to adjust this item. Where are you located IMUL that it made a diffence after you adjusted it? Which way turning the screw does what? Where did you notice the difference as well, from a dead stop accelleration, top end speed, hill climbing without losing speed, what? I'd appreciate any input you can provide, as well as how much the screw was turned, and whether you can tell if you've gone to far etc. Any written guidelines anywhere that you know of, to set this little fellow to operate correctly, or increase performance in one way or another?

Charles
