Why is this starter not for carburetor cars??

[falcon fanatic]

I just acquired a powermaster 9103 starter (http://www.summitracing.com/parts/PWM-9103/) and there is a tag on this unit that says, among other things, "Not recommended for carbureted engines." Why in the world would that be?

I find that statement to be bizarre and worthless, on the page you listed, their "Application" tab you can limit the view to L6 Ford engines and it lists the 300/250/240/200 only 1 of those was ever offered with EFI.

Install it, you'll be ok.

That makes absolutely no sense, EFI or not, its going to be doing the same thing. Maybe it means the starter is built like shit and cant handle the longer cranking carbed engines need to run?

Is it possible that since it's a PMGR - Permanent Magnet Gear Reduction, it uses big arcing commutator brushes which may ignite carbureted engine fumes on start, especially with choke?.

Or maybe different pitch FW teeth with later - Injected engines?.

Offshore manufacturer translation?..

My guess would be the extended cranking that is more likely with carbs. Ever take apart a modern starter? Everything is tiny and often plastic. They seem to work fine for short periods but I cant imagine they would hold up for very long.

I called them. BAsically they said in a high displacement, high compression v-8 they've had instances of people starting carbed cars and getting "kickback" which damages the starter. It's a 160 ft-lb unit and they want you to buy a torquier model for performance v-8s. In other words, it's a non-issue for me.
