    Default First run on 582 gray head and having issues

    I got her to start but runs really rough. Sounds and feels like a dead cylinder. Watching the egt's first one then the other goes cold. I'm not a real fan of two stroke engines but that's what it came with. Besides pulling the plugs, any other ideas?

    I found a clue! Oil out the exhaust. When I bought gas I mixed it 100:1 as the oil injection system was new and dry. Looks to my untrained eye that there is too much oil.

    If you are mixing the fuel at 100:1 you would be using 1.28 oz. per gallon of fuel. I doubt that the motor is getting to much oil if the fuel to oil mix ratio is truly 100:1

    Yes, but the oil injection should be working too.

    When I first ran my 582 I mixed oil into the wing tank fuel at 50:1 as well as having the injection system serviced. It ran just fine with both sources of oil. Starting the engine for the first time I wanted to make sure it had adequate lube if the injection system wasn't working.
    Nowadays I still mix 100:1 AND use the injection system. Runs fine!
