SU Carbs 140-160 1970

New SU user...switched from Dual Mikuni to HS6 (latest version with butterfly return springs)
HS6 mounted on much modded B20 (no spacers) monkeyfied extra return springs from butterfly ear to top of head...

Currently running, accel seems fine...decel seems "delayed"??? Is this function of piston return spring, or too heavy damper oil (using ATF)???

Am used to immediate decel that Mikunis gave...
