    I am far from an expert but the plugs look much better now than before. I think you are heading in the right direction. Earlier plug pics looked very lean compared to these. Hopefully that continues...

    I burned up a piston twice in cylinder 3. It appears it was from a lean condition. I have done so much work I don't know for sure what the cause was. I did have air in my fuel line especially when...

    Pressure test the fuel system to make sure you don't have a leak. It doesn't take much of a leak to create a problem.

    I am a rookie in terms of mods but I have read enough to know removing the stock spark arrestor and adding aftermarket ones cannot be done without modifying the carbs. In other words don't do it...

    I bought a $20 used stock replacement sensor on eBay. If it works I should be able to check it against my phone so I can compare it to the real world speed. I know the stock sensor is inaccurate but...

    My speedometer doesn't work. The Candoo pro GPS Module seems like a good option for me. It is a bit pricey but it would be nice to know what my real speed is without having to use my phone. I will...

    Why did the slime build in up that carb? Maybe it was just neglect?

    I truly hope you are lucky and it is running perfectly going forward. I did not have that luck...

    No. You can't not remove it. The oil pump feeds the three carbs as well as the counter balance shafts at the front and rear of the motor.

    Pulling the pump is fairly easy. It is a good idea to inspect it so I would pull it. They are known for only lasting 50 hours or so before they need to be rebuilt. A rebuild kit is fairly inexpensive...

    No I did not. Try swapping one of the fittings to see if the issue is the head or the fitting itself.

    I ordered my triple pisser kit from Skiworx last year and it also came with Husky air line hose. Mine is yellow but it is the same stuff. It worked perfectly.

    The nipples appear to be fine. From what I understand the hose clamps are there just to hold the line on. Not to seal it. Which means to me the line is too stiff to seal against the petcock nipples....

    You should probably start a new thread about your issue. Or read this entire thread and you might find some great ideas about what to check first. A compression test is easy to do and only takes a...

    If it is running that well and at those speeds I don't know if I would worry about it. Like kartracer said you could pull off the cylinder heads to inspect the cylinder walls and tops of the pistons....

    The problem is that they may run great on the trailer but once the pump is under a load in the water it may not. There are so many things that could be wrong. I bought my first ski this spring...

    I have also recently gotten into the STX-R/Ultra 150 skis. They have the same motor. It is common that they can be hard to start. Everyone here recommends installing a primer kit to fix the issue. I...

    All I can say is I am very sorry guys. I am an idiot. I am going to water test it now. I thought the throttle cable was not being pulled but when I removed the bracket the ski would not stay running....

    I get it. I shouldn't have bought this ski. I should have dropped $10k on a new 4 stroke ski.

    Unfortunately I did buy it and I am trying to get it running properly. If you can help me get it...

    I couldn't find Peter's post and I don't know exactly how many feet I need anyways. I just ordered 25' from Walmart. That should give me plenty and it is the proper hose to use. 25' of Tygon fuel...

    I just finished testing the compression. They are all between 126 and 129! I believe that is perfect right?

    I tested with all plugs removed and the engine cold. I had the battery on a charger so...
