I second that opinion

A Mikuni rebuild is gonna take time finding parts etc final adjustments after reassembly is something I have not mastered (yet) it won't be cheap part$ ~ and IF all the support emissions mechanisms vacuum actuators solenoids temp O2 sensors etc etc ALL that stuff connected to the ECM must be working in order for the Mikuni FBC to operate properly...
