    25 hp Power Pack?

    I think I'm having multiple issues with my motor (2000 25hp Johnson). Like I mentioned in my previous posts this motor just won't run properly. I took the lower end of today and it is full of oily grey sludge. I have checked spark few times with a spark tester and 7/16" gap and spark is bright...

    2000year Johnson 25hp timing things...

    Hey, I bought this engine 2 months ago. I've already fixed the carb with a rebuild kit and cleaned it real good too but I still have a problem in slow/idle speed. It acts like running a bit lean but the idle mixture screw is out about 1,5 turns and the carbs passage ways are super clean. Running...
