need new carbs for tunnel ram

im on a pretty tight budget, so im looking at doing this the cheapest way, yah i know nothings cheap and its an endless money pit, my uncle told me the butterfly,s are screwed or something and that rebuilding them is not worth it, i personally dont know anything about carbs especially thows exept for kinda theoretically how they work the ones pissin fuel out the opposite side the throttle linkage is on threw the throttle thingy with the spring, if i can rebuild them i most definitively will, i guess il start reading about carbs, thanks for everyone help, and il let you know if im going to sell them
