My rebuilt ’81 Special has Mikuni VM26-8074 carbs on VM28-200 manifolds with UNI UP4182 filters. Starts/idles fine; air/idle screws 2 turns out. Problem: won’t rev, smells rich. Manual petcock, dual fuel lines with filters, valves set correctly. Anyone familiar with these carbs or the Speed Moto kit?
