    Are there any clues I could look for that would tell me my motor is running too lean? Other than looking at the spark plugs?
    Thanks!

    Install an EGT somehow

    But you will need a baseline... when temp rises You will know you are lean ....

    If it's a 2 stroke, by the time you figure out that you've been running lean
    the damage is usually already done. Engine has been running hot
    not properly lubricated and components are already starting to fail.

    Doesn't take long at 5200 rpm... :-[

    I run an EGT and CHT on my ROTAX s

    You have to really watch ... I HATE Dead Stick Landings !!!

    There are setups that have settable Alarms ...

    Thanks guys. Had a little linkage issue (if you call falling completely off an issue! :eek:). So I wound up just starting from zero and resetting the idle speed jet. I am sure it fine. Just got a little paranoid (again).
