    as far as i know, the 'right' timing should be '10', however my mechanic says it's ok to have it set to '12' as this will give me a better response. i noted that after this was done, my fuel consumption increased, though this may also be caused by the air-fuel mixture on my carb and other factors... i'd like to have a second opinion whether i should readjust it to '10' again to regain my old fc... any thoughts?... thanks

    Dod,
    For a 2E engine, ignition timing varies on the fuel you use. I'd suggest 8 degrees BTDC if you're using unleaded 93+ octane fuel. 10 degrees btdc if you're using premium 95 octane fuel; and 11 or 12 degrees btdc if you're using 97 octane fuel.
    Have your carb re-check the adjustments of idle mixture and idle speed screw. And be sure your valve clearance should be correct.

    Hope this helps.
