    I guess based on what I found, paper towels are not a great thing to use when cleaning a carb.

    I think the enrichner problem was more the culprit than the paper towel. The paper was stuck between the needle jet and the holder, and while it might affect mixture it would not change dramaticly from one run to the next. The enricher could stick and give a total different run from one start to the next. My thoughts Proof will be in the run tomorrow (depending on weather).

    Yep. Enricheners can be an often overlooked problem.

    Did you disassemble any further than that? Did you weigh your floats?

    Yes cleaned everything including main jets, low speed jets, mid range, enrichener circuits, but to be honest did not weigh the floats or remove the float needle. I also removed the diaphrams and inspected. As you said they were keyed and easy to put back in the same order. i am excited to see the results I will install tomorrow, balance and let you know if there is an improvement.

    all you need to do with the floats is look at them when you remove the bowl. if you are careful you can SEE how the float works, if it sinks, it's bad. that's how I found a bad one a few years ago on my ul motor.

    They were good when I removed the bowls with the fuel in them. I did not want to remove the float needle as I have done that before and was never sure I did not bend the level out of spec. I will try this first.

    I put an hour on the Fox today after cleaning the carbs and I am happy to report it is much better. Not perfect as there is a high frequency buzz type of vibration but it is much better. I will continue to work on it and see if I can get it perfect.
