[QUOTE="Tazza, post: 129653, member: 82"] As you know, smoke at startup is normal, especially if you use the excessive fuel button. If it starts nice and easy, i'd feel that your compression is still good. Smoke after startup could be an injector issue, if the spray pattern isn't good, it can cause smoke while running. If it's using oil, i'd suspect there could be cylinder wear if you were using oil and having blue smoke. Sadly i'm not a mechanic to be able to give you specifics, i'm just a lowly office person. There likely is a max fuel limiter screw, but i believe that will only come into play when you are putting it under load, it limits how far the fuel rack can move so it is unable to pump in too much fuel to air that would normally cause smoke.
