Re: Low RPM's

Andrew and Brian,

 Franklin  66-76" prop.

That pitch should be OK if the prop is thin.What brand of prop?
Thickness?  Cord?

Other factors that effect static:
Advanced timing....is it running hot?  New mags can be timed wrong
internally and check out OK with a buzz box.  Jeff's electronic should
be fine but easy to check. Have you done a static on just the mag or
just the electronic?
restricted intake...airfilter?
Fuel flow.. fuel pump...fuel filter....carburetor?

Ideally it should static 300 rpm below max rpm for best all around
