As for the fuel screws, the ones you get with jet kits already have slots for flathead screwdriver. It's just the stockers that are wierd. Do ya'll call em flathead screwdrivers in the UK? I have no idea what proper name is...slotted tip maybe?
    yeah flat head screw drivers.

    On the earlier models, they have an inline filter just before the fuel pump.

    If you want to go poking around in a jet to remove dirt, get a bit of thin electrical cable, cut 1 copper strand and use that, as its plyable, small and wont damage the jets. (im talking normal wiring harness thinkness, say indicator wire thickness but 1 strand)

    Here in the south...if someone mentions "flathead", they're either talking screwdrivers or catfish

    haha, I'm pretty sure it's "flat head", though i am going to start calling them slotted tips just to annoy my friends now :P

    this is a good write up!
    I can't stress the importance of smooth, clean slides enough!
    be sure to clean them intensely with carb cleaner (do not oil them!) and make sure that the diaphragm has a good seal. The slide lets the fuel into the engine, if it is binding, or not functioning properly you aren't getting any fuel into the combustion chamber!

    You my friend have a float stuck. Did you clean needle and seat? I can't remember if that was covered, but I clean the seat with a Qtip soaked in B12 cleaner then blow it out to get cotton fibers out of there. If thorough cleaning doesn't help, you may need new needles. Btw...if someone suggests adjusting the float, forget it. They are non-adjustable.

    If you have any mechanical experience at all, you can do it yourself (and save some dough). It's not hard at all. Worst case scenario, if you get in a jam you can just snap a pic of problem and post it on here. Several people on here with carb experience. Where is Granite Falls? I've lived in Wilmington, NC for a few years. NC is a very cool state!

    legal disclaimer...If you get to a point that is outside your "comfort" zone, STOP and put it back together. I can just see someone coming on here and jumping down my throat cause they botched the job.

    BTW, you need to be a contortionist octopus to get those long springs back in after cleaning everything

    A little patience and a lot of logic also helps.
    You know how it is when you lean back too far in your chair and almost fall backwards, but save yourself at the last second? I feel like that all day.

    300 bucks!! sheesh. I normally charge 25 a carb. It's not nearly as complicated as you might think. Have you ever worked on any type of carburetor? Hell, ship em to me and I'll clean em for you. 300 is a rip-off. PM me if interested. I can give references (from members on here).

    no way to sync them off the bike. You might be better off getting that done locally then. Sorry, wish I was closer or I'd hook you up.

    Actually, if you were to hurry, I could stick them on mine and sync them. I haven't torn it down yet. No sense in taking them somewhere and getting screwed up the ass when you get the bill. I'll treat you right.
