    GSX cleaned carbs now leaner on PTO? only 6600-6700rpm?

    Did some preventive maintenance by replacing the fuel lines and cleaning the carbs, I didn't rebuild them as the ski has only 35 hours now and everything seemed fine.

    So after I got it out on the water this past weekend I noticed right off the bat that it didn't reach top rpm after a few tests. Checked the plugs and it was hotter on the PTO golden brown vs mag which was a dark purple/black.

    I backed the high needle out a full turn and it didn't help much, alittle but not much.

    Question: is the PTO to lean or is the mag to rich? Could it be the base gasket leaking if its to lean?

    I have this week to work on it and test it. I'm not a carb guy you want me to program your turbo/NA honda I can help but this is my first carb I've worked on.

    I just looked up the manual again and it looks like I put that metal filter in backwards, so I'm going to switch that around and try it again. I can't see that giving and issue with only one cylinder though.

    So any thoughts on what else I should do?

    Remove your fuel selector switch and disassemble. The rubber sleeve inside can shift and block fuel flow. And, they can gum up from the bad fuel lines too.

    That would make sense if there was a lean condition on both carbs, but this is just the one.

    Since I took both carbs apart and cleaned them and the ski ran very strong before I'm guessing I messed something up.

    So I guess the question is what did I mess up?

    It would make more sense if you would stop assuming both had to be lean. That is..."if" you assembled the carbs right. Try it and then report back.

    BTW...a pic is woth a thousand words. Shoot one of the carbs with the f/a removed. I want to check fuel line routing.

    funny you mention that about the fuel line routing, I didn't take a pick before I removed them and I even did a search but couldn't find anything relating to the fuel lines.

    Ok so its T'd off, one goes to the front of the PTO carb, other goes to the front of the MAG carb, then the rear PTO carb goes into the Rear MAG carb. Is that right?
