    I'm not sure this is that good at all...
    I was going to just slot this set of carbies in to diagnose an ignition/fuel system fault on cylinder four and thought I'd better give them a clean up. 8O
    I'm not sure what the fluid is but it has the consistency of PVC Cement.

    Lots of neglect and abuse to those babies.

    What you've got there is really old fuel that's turned mostly to varnish with just enough moisture to rust the steel parts.

    As soon as the market opens Monday I'm buying stock in carburetor cleaner companies. I think there is going to be quite a rally in that industry. :wink:

    i'm with micarl, those carbs are gonna need a case or two of cleaner and if the carbs are that bad i can only imagine what condition the petcock and tank are in maybe a few shares in tank sealer stocks would bolster my portfolio :lol:

    I had bad experiences with the tank sealers and ended it up costing me more at the end. So it went to a rad shop sealed and spot welded the pin holes the acid left and for 85$ she's ready just need a new paint job. My 2 cents for the tank sealer stuff.

    Be careful of the fuel you use as well. The ethenol burns cleaner and that is great for the environment.... for cars. But the ethenol leaves gooey deposites on everything and these bikes were made at a time when gas was... ummm... gas. I had a 1981 Dodge Diplomat that I messed with a lot and put a new 4 barrel carburetor in there. Oh yeah. Ran only 91 octane with 10% ethenol in it (trying to be environmentally concious) and when I cleaned those carbs about a year later the components were actually sticky. There was goo everywhere and My valves were just as gooed up. After cleaning them and reinstalling everything, Doug, our car guy, told me the horrors of ethenol.
    I blew that motor up racing a kid in a neon (srt 4) right after he handed my ass to me in that drag (haha... those things are fast) and out of curiosity I tore the carbs and heads apart. I had been using nothing but shell 91 octane in a non-ethenol formulated county. My carbs were almost as shiny clean as when I had first cleaned them a year or more prior. Same with the valves.
    Once everything starts getting gooed up from the ethenol, it just traps all of the other nasties in the gas.
    Once you clean those carbs out, try finding a place without ethenol in the gas or buy "real gas" from a shop.

    Every 5 or 6 tanks I always put im a bit of "Fuelstabil" in the tank. It's at the autoprts store, walmart, and most other places with a decent auto section. Clean bottle with red liquid. Keeps everything nice and purty.

    I have to admit its a nice shade of green.
    I was thinking of giving them a petrol bath and hitting them with the tooth brush first to loosen up for the carb cleaner. I like what the carb cleaner does but the nitrile gloves I wear for this type of thing don't seem to like it and they end up with gigantic balloon fingers, also man does it smart if you get a miniscule overspray drop in the eye (time for some better goggles maybe)
    Still I will be purchasing vast quantities for this new project and looks like another order to chacal might be coming up.
    I must get back to the original cylinder four problem of not producing except with the fuel enrichment circuit enabled, any ideas? I have a spark and fuel in the bowl but at idle it runs like a three cylinder and according to the headers(water test), cylinder four is practically cold at idle, which is damn lumpy, whilst the rest are hot and cooking.

    I would attack those with a Acid Brush and a Trigger Bottle Sprayer.

    Have a Basin and place the Carbs on a large Toaster Oven Grate that will let everything drip off the Carbs.

    Hit them hard with a couple of cans of Carb Cleaner.
    Tilt the Basin so that the Cleaner all collects at one side.

    Add some Hose and a "Screen-type" filter to a Trigger Sprayer and reuse the Carb Cleaner until you knock-off some of the real nastiness you have to deal with, there.

    Once you start making progress, ...
    dump the filthy Carb Cleaner out and keep playing the same song.

    Them-there is the sort of Carbs I brings-over to my local Ultrasonic-guy with some new money or a Duncan Donuts Gift Card.

    When I first got my bike, #4 would stay cold and maybe only get luke warm. THANKFULLY :wink: my carbs looked nothing like yours. Cleaning and syncing fixed the problem...

    Pulled the carbs out again and re-cleaned the enrichment circuit and it was blocked, man I was sure It was clean... must of missed it while cursing the carbie cleaner in my eye :(
    So, the bike starts and is getting close to running properly as this was a rebuild from scratch but as you can see I have a second set of carbies, albeit green, they may come in handy so I went to work on them and only used 2 cans of carbie cleaner, 500ml of lime juice(boiling the bowls sorted out the enrichment circuit straight away and they came up really nice, I wish I had boiled the jets too but cleaning the enrichment circuit was the aim at the time), 2litres of Unleaded petrol and one toothbrush.
    Unfortunately one of the pilot screws is headless and I will have to work on that another day but I now have a less green spare set of carbies which are soaked in inox for fear of corrosion till they are put into use, thanks again for all the advice.
