Hey guys, I have a problem I hope you all can help me with? im running dual carter yfs on my 235 and they have a stumble of idle, they have been rebuilt with auto parts store generic kits (I didnt know any better at the time). I have synced them with a snail style vacuum gauge, im running 5/16th line which is just a hair smaller than stock. it idles pretty good and runs really well at higher speeds. if anyone could maybe point me in the right direction it would be greatly appreciated!
