Engine Tune
 

Ok this is a dumb question but i havn't messed with my nexstar for awhile it has the .46 FXI on it, it was running kinda lean the last time i had her out, so i was wanting to tune it a lil richer,, but i can't seem to remember which way is richer clockwise or CCW..
I know this is a NEWB ? but i can't find my book either.


Also is it better to have it run richer or leaner ???

Thanks
Tim

I beleive counter. but i tend to get confused myself.

CCW=out=richer
CW=in=leaner
Fire it up and go wide open,leaning it a little at a time until it gets peak RPM,then richen it about 1/8 to 1/4 turn.Hold the nose up and see if the rpm comes up,if it does,then your pretty good,if it revs and dies with the nose up,richen the mixture another1/8 turn or so.

Let 's see if I can help you remember. rightie tightie screwing the needle valve in..cuts off fuel or leans it. leftie loosey screws the needle valve out opening it up or richens it

Figures a Jet Mechaninc would come out with that :D

Okay, so , what happens if you use your left hand on a "rightee tightee and right hand on a lefty loosey?":D Sounds like the old "BOO" method on the definition of a ceiling

Left and right are the same with either hand, but admitedly you have tho think more if your right handed and using your left hand.
