    Tohatsu carb - RICH / LEAN screw which way?

    I can't find it anywhere in my manual. It's a M40D2. I'm thinking rich = screw OUTwards and lean = screw INwards? Thanks

    Correct start procedure on hard-to-start 30hp Suzuki

    '95 suzuki DT30c is running beautifully but is a real pain to start - I usually end up flattening the battery.

    Suzuki DT25c carb, will it fit a DT30c???

    To cut a long story short, the idle mix screw on the top carb of my 1995 DT30c had seized to the carb body - a screw extractor failed to get it out, so I'm stuck!!! I can source a top carb from a DT25c 1989 model. It's a long shot I know, but does anyone know if the carb body is the same? I...

Maybe it's supposed to be red??? it's a 1995 Suzuki DT30c, 3cylinder - 2 stroke, oil injected. The...
