    1200 bogging down midrange

    I been having a problem with the ski bogging down midrange like it's going to stall. I pulled the carbs today they looked pretty good bill had done them 2 years ago. But I found 1 internal filter clogged with sand the others were in good shape. The plugs looked like they were running lean. Would a 1 clogged filter bog me down and cause the ski to lean out? Running pre mix

    Short answer: yes

    You lean out 1 cylinder, you loose 1/3 of your total power assumeing you have 3 cylinders. Have you checked compression?

    This showed up on the break in of a new engine once I got to the 50% throttle she bogged down. Which was the same problem that caused the original melt down. i pulled the plugs they looked lean and having just changed over to pre mix i did not notice nearly the smoke i was expecting. i neglected to open the carbs up during the rebuild because I had them done last year. Lesson learned the hard way. I got everything back together yesterday with the new filters and now I'm happy to say she is running great. Plugs are looking as they should for a engine being broke in and I'm leaving a trail of smoke across the lake
