Moroso rev limiter

[mockingbird812]

Anyone say how well/accurate these style of rev limiters are? Do you set via trial and error. I assume the hex nut on the slanted slot is the means to adjust the upper rpm point.

Thanks,

We used to stick a distributor in a distributor machine and set them in the shop instead of doing it on the car. The distributor machine would let you see exactly what the rpm was when it kicked in without having to do it by trial and error.
