new guy to the forum. I have a 1975 CB360 that is getting under my skin because I can't figure the thing out. The bike starts up first kick, idles, then when I drive it I usually only make it about 2 blocks before it's dead with fouled plugs. The plugs are dry, black, and sooty.
I have been through the carbs because I read that meant it was too rich. (?) The carbs were pretty clean, but the floats were a little high so I lowered them to 18.5mm. Carbs back on.. same thing. fouled plugs. I adjusted the air/fuel mixture screw in, same thing, starts great, idles, then fouled plugs.
I then replaced the coils and condenser with a used set off ebay. same old story, starts, idles, fouled plugs. Battery has been checked and is fine, fuses, fine. Fuel filter is clean, petcock is running fine, air filters seem ok. I even ran it once with no air filters on and got the same end result of fouled plugs. Can you guys solve this riddle for me because i'm about to lose it! For some reason it can't handle the load of riding and fouls the plugs and there I am again, doing the push of shame back home. Thanks in advance.
