Just another 1 to 1 perspective here, dual forward/normal facing quick fuels on an RPM air gap. (required offset spacers)
I did it for better distribution in a unique manifold/carb combo, to be different, and for the setup challenge as a newbie, it was a challenge.
70mph cruise comes in by 1/8 throttle at most so there is a lot of dialing in to do at idle/transition and barely into mains for no-hassle street use.
I like it, it's fun, be ready for some carb. tuning though and it is a pain to have to pull at least one carb to get to mains. (not an issue for sideways of course)
I think the pedal to carb linkage in my Thunderbird is mostly linear, a non-linear linkage yet retain 1 to 1 would improve low speed throttle control.
And yes, it's a pig for anything other than constant throttle cruise, maybe I'll make it a hybrid!
