You cant get the stuff we used to that coined the phrase "boil out the carbs" so what I do now is , Get a crock pot add Dawn with water, using Berrymans or old school carb cleaner can have chemical reactions, especially with the plastic parts, although Dawn is on the low end of the harshness scale. Certainly less so than carb "dip" but still a good idea to keep an eye on it as it cooks. Dawn or what ever and cook them for a day or two.
Make sure you get all the small o rings out that are buried in the carb body, like the air mixture screws and take note where they went and get new ones. Get an electrical cord and use the single strands to do the small ports etc. Get a can or 2 of Carb Cleaner and shoot it into a shot glass, put the pilot and main jets and let them soak for a day. Put the tip on the carb cleaner can and start blasting out every port, then push the wire back in them and douche them out again. Rinse in hot water and blow them out 1 more time with a air compressor.
The Pilot Jet holes are small, like really small, Hold them up to a bright light, If you can see a dim glow in the center there clear, No visible light in the center they are plugged. Ive never been able to find a wire that will go through the center, So soak in carb cleaner and use air pressure to clear them out. Also I always screw the air / fuel mixture screws in all the way before I install the orings and count how many turns in until it bottoms out. With the orings in you will start feeling resistance and those screws and seats are very fragile. When you know how many turns in once the orings are installed you safely know how many more turns in is bottomed out.
Carbs are mechanical big time, there is not much to adjust, if all the ports are clear and clean they will work. when reassembling them use some oil on the o rings so nothing gets torn, Also the diaphragms will likely be all out of shape, so use some axle grease in the groves of the carb bodies to kinda glue the diaphragms in place so when you put the lids on they stay where they need to be.
Once you get the carbs all put back together with the bowls OFF but not on the bike, hook a hose to the fuel inlet that feeds all the carbs. flip the 4 carbs assembled upside down and blow air into the line.
You shouldn't be able to blow air through. Keep feeding air into the line and 1 carb at a time manually open each fuel valve and air should start coming thru, then close and no air flow. Do that for each carb and make adjustments to get all 4 working. Also when the carbs are upside down make sure the floats are all level.
Its a lot easier to get all this working off the bike.|
you can do it, piece of cake Bro !!!!
