Just spent another 40 bucks to rebuild these damn carbs. Put them back on and I still have the same problem of carbon building up on the plugs. Could the PO of the the carbs made the hole in the jets bigger? Can I have this problem because the rings haven't seated yet? I know the valves need adusting could any of these be the cause??

yes. jet guages are made for this purpose. it's fairly common to ream small, lesser-used jets to bigger sizes.

it's also possible that your plugs are simply way too cold. what kind and flavor of plugs have you got? are you using the stock ignition system or something else ? are you using the proper grade of gasoline ?

it could be a ring seating problem, i suppose - it is oily or just sooty ?

i wouldn't suspect the valves of this but if they need adjustment, do that.

have you run any kind of exhaust-gas analysis? what do your CO and HC look like ? is your timing correct ?

exactly what sizes of idle, main, and air correction jets do you think you have (pending gauge verification...)? what is your altitude ?
