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.

That makes sense! Thanks John. Did they stay adjusted to the max rpm that you wanted or did they wander?

You can't see it in any of the posted pictures, but the three set screws in each slanted slot have a hole through them. I assume it is to use twisted safety wire so they can't move.
