Default Starting Vibrator mounting

For planes using retard magneto's,

where do you mount and in which direction do you mount the starting vibrator?

I would mount with plastic shell upside but it looks happier if mounted down, terminals facing the sky.

Is it ok to install on the engine side of the firewall, mounted high? I think I have room above and behind the magnetos as long as engine temperature is not an issue.

Should I avoid behind the firewall near gas tank due to possible sparking, even though the tank vents below plane?

For twins it is placed a long way away from the engine as they apparently only have one for both engines.

Never seen one on a single engine plane (but have seen one on a helicopter in the engine areaa).

Mine is mounted on the engine side of the firewall in the upper RH corner. Cover down.
Haven't had a problem in the six years I've owned it.

Yeah cover down makes more sense when you look at it. I am just so use to cars that I would call that a moisture bowl. Engine side makes more sense as well and I do think I will have room at top. Just not sure about heat over a long period of time. The MGL RDAF should be able to live there as well.

thanks,

Default Me too...

My Duster came with it in the middle of the firewall, decided to mover to top like you were considering, then I made a new firewall so I'm mounting on a removable board mounted to the battery box with the solenoids and other electrical stuff. Heat is probably only a problem when your restarting after flying I would guess.
