AnswerHello Yannic,
I've done the same thing before, with the same results. The reason for the heavy smoke, (usually tinted brown), is that the inlet needle sticks open inside of the carburetor, and allows the sled to flood to an extent, but still run. you probably already know the basics, but I'll just put them down, in case you need a reference. I'm not sure if you have an air box, on the carb, but if you do,remove the clamp the tightens it to the carb. Then loosen the rubber flange from the engine/to carb mount, and take the carb off. The carb will still be connected to the throttle cables and choke cable, but that's fine. Turn the carburetor sideways, and remove the four screws that hold the " float bowl" in place, on the bottom of the carburetor. Inside the bowl, that detaches, there is 2 plastic round floats, generally brown or black in color. Spray large amounts of solvent on the carbs parts inside. Work the two floats up and down, until they move freely. Then, there is the important part, the inlet needle. It has a arm, that moves up and down, and is attached with a thin rod, on two posts, protruding from the carbs body. Take a thin nail, and push the pin out, and then remove the float arm. Then, remove the inlet needle, if it is hard to get out, spray some solvent on it. It's a good idea to remove the inlet needle seat too, with a socket. Now, there are two things to do, clean the needle and seat very good, and carefully, which works good most of the time, or buy a carburetor kit, and install new ones. Www.denniskirk.com , or www.mfgsupply.com , have the carb repair kits for the Jag. Whatever you decide would be best, be sure to hold the carb up-side down, and check the float level. Here is a site that tells all the specs to that carb, that I can't fit on here: http://www.mikuni.com/pdf/vmmanual.pdf . I would recommend a new set of NGK BR8ES plugs, too. I really hope this helps, and that you can get it running good, with out all that smoke! Let me know if you need any help at all! Good luck with the Cat, the snow is coming soon! --Arcticatman
