    Make sure to get a filter that fits a 1/4" fuel hose.

    Where abouts are you located?

    Hahaha, up until 3 months ago I lived around the corner from flying squiril motorcycle and didn't even know it was there. I'm near dufferin/bloor now but I'm in the east end fairly often, I'll check it out next time I'm nearby. Thanks bud

    An inline filter can cause more problems than it is worth...I would say don't bother.
    Do everything else mentioned and rinse the tank a bit with fresh gas to get out any remaining particles.

    The filter sock on the top side of the petcock should stop anything that would bother the carbs, check and make sure it is still in place and working well, no holes etc.

    As long as it is replaced regularly it should not cause problems. Can you explain why you think it would?

    So I pulled out the carb today and have it a cleaning, but it didn't solve the problem. I'm getting some pretty thick looking exhaust now, and it sputters quite a bit when giving it any throttle. There was a lot of gas inside the carb when I pulled it off, each section I opened drained a fair amount. Any ideas?

    How long did you let it run?
    What position is your petcock in? off, on or reserve?


    Did you let the carbs sit in carb cleaner and throughly clean the little holes in the jets?

    They restrict flow, particularly in a bike with a gravity-only feed. They are fine on bikes with electric pumps, but not on old bikes like mine.
    I tried one on my bike back when I didn't know better...all it takes is an air bubble in the filter and the bike won't even start.

    Sounds like his slow/pilot jet is plugged since it is 99% responsible for fueling at idle, or there just isn't fuel getting to it.

    His float height may have changed but...if it was running... Usually if they sink they cause the overflow to piss gas...so I doubt that too now that I think about it. He could just pop off the cover to see if there is fuel in there and what sort of height.

    The biggest culprit is him using old gas..it is likely much older than he remembers and isn't good for much except cleaning parts now.

    I'd go back to the earlier suggestion...drain gas, remove petcock. Flush with new gas from a clean container. Rebels have a small screen in the petcock iirc from mine 25 years ago...clean that too.

    I would much prefer to swap out a $3 fuel filter than disassemble the carbs to clean out the jets because some crap from the tank got in there.

    Just make sure to get a see through one. This way you can see what's going on easily (dirty, no fuel, etc).
    Be sure to get a filter for a gravity-fed fuel system. Not all inline filters are ok for gravity-fed fuel systems!
