    Towed some Folk

    One day in 2011, I was out boating, and ran into my Manager on the water. We chatted a couple of minutes, and went our separate ways. An hour later, I was making a run to the far end of the lake, about 13 miles, and I saw a boat sitting at about the Dead Center of the Lake. On my return, the...

    Booze and boat don’t always mix well.

    In 1976, The Old Man drove the Boat up on the Beach like that. He told me to put the Boat back in the Water, as he went to sleep it off. The Transom was about 10 ft from the edge of the Water, It took a few Hours of digging the sand to make a Canal next to it deep enough, and a few people with...

    Yamaha 130 v4 idle mix screws

    Two Strokes do tend to Load up at Lower Speeds, Nature of the Beast, but an Overly Rich Mixture will certainly speed that up. Factory Spec?

    Where did you come across the Plate needing a Hole? Perhaps the Engineers decided the Throttle Plate needed to be closed more, in relation to the Idle and Off Idle Ports, and a Hole was needed to restore the Airflow

    40hp Dead Top Cylinder
