    It's hard to see in the spark plug hole, but it doesn't look too dark. Granted I haven't run it much. Turning the screws helped a lot, and I ordered some jets just in case, but it's much better. I...

    Check. Would you go up to a 112.5 or 115 or more? Or can't I really know until I test them? It idles fine, but I do have that stutter in the acceleration sometimes...

    I checked the pickup line in the gas tank - didn't realize it was an aluminum tube, so that wasn't blocked or plugged or coroded. I also bypassed the fuel selector...

    My pto cylinder is the one that has about 100 (and climbs slowly from 90). I can test again, but that's what I got last time. It doesn't 'feel' like a fuel delivery issue per se, but I can't be...

    Follow up questions:

    Increasing the size of the jets makes sense to me as the pistons were bored out 1mm over and the jets are still factory sized. I could see where the increased volume in the...

    to clarify, the second clip doesn't show an attempt to get to full throttle, just the weird thing it does - it was maybe 3/8 throttle at the time.

    Ok. Here we go.

    I reinstalled the reed valves with new gaskets all the way around. I trimmed the spring in the 1st carb to match the pop off of the other two (roughly). I put new gaskets on the...

    Main jets are stamped 110 on the top and pilot jets are stamped 67.5. Are those within parameters?

    Shavings might be from a screw I had to drill out in that carb that I forgot about - I tried to...
