twin 40s FTMFW they are mint ,once setup there just pure awesome ,but you cant just degrease a set and bung em on

i tryed that and was pulling hairs out trying to tune them

if you start with carbs that havnt been tampered with ,have good throttle plates and shafts ,and then put kits through them and replace any adjustment screws ,like pilot screws /idle air

and a good manifold with decent linkages ,such as a bprojects kit ,awesome manifold anf the linkages are the best ive seen for a over head rail setup ,the shaft wont twist/flex like the redline ones do and the bpro kit uses the factory throttle cable which is pretty cool and means if the carbs become a problem you can just chuck a stock carby back on

well worth the time though ,twin weber/dello/solexs are mint
