    No, if the choke cable falls off, they just stay open and youíre not able to choke the motor. Chokes are spring loaded. My guess is previous owner had the carb out, and forget to tighten the nuts...

    Yeah man, I live and die by that manual. The rear carb is setup identical to the front and middle.

    I need to get around to pressure testing the motor to make sure I donít have a leak.

    Took boat out again today. Left motor bogged and RPMs were low. Like itís running lean.

    Right motor felt very responsive and strong, just like it did right before it melted the piston.

    If refreshing the fuel pump side of the carbs doesnít fix the issue, Iíll do as you said and pressure test the engine.

    Talking about the drilled return mod that OSB had posted? Yes, the returns are drilled out to 1/8" in each carb, and a 95 main jet placed in the fuel return line.

    I think I have a pretty good understanding of engine theory, and I don't see at all how a reduction in back pressure calls for a smaller gapped plug. If you could expand on that further, that would...

    How do d- plates affect spark plug gap? Everything I've read says the XR1800 has a higher powered ignition system, hence the larger gapped spark plugs.

    Yeah, I'd love to know why the GPR got 95 lows and the XLT got the 87.5. The stock setting in the Yamaha manual shows both the low and high speed adjusters opened more on the GPR than on the XLT. So...

    Good deal. Like I mentioned earlier, common consensus on the jetboat board I frequent is to swap out the 87.5 low speed jets for 95 jets to richen up the bottom end. Since you kept the stock 87.5...

    Bogs down when given throttle, then clears up and runs fine. If I cruise around, cut throttle, and get back on the throttle, it does fine. If I idle around, it bogs again when given throttle.
