Default FM Auto clutch questions

Not sure where to post this

Friend lost his left leg above the knee last year and wants to ride again - his bike is a mutt late sixties shovel top end with a ratchet top 4 speed kick only and a tin primary , foot clutch hand shift
Question is has anyone used one of these auto clutches with a tin primary
Info from Fm says they work but you have to drill a hole in the derby cover and turn the adjuster in 1 1/2 turns then start and back it off again and away you go but this has to be done every time you start the bike , my bud is not the high tech guy and may have misunderstood the directions but asked me to check if anyone is running one and how it works

Thanks

Dave

what I have seen is:

add a conventional HD mousetrap clutch booster spring- instead of mounting the lever on the handlebar, mount it ON the tank shifter.

his left hand can work clutch and move shifter at the same time.
