Does anyone have any suggestions on how to hold the two rubber cushions in place while installing the magnetos?

thanks

Use a dab of grease under each. Should hold good enough.

What rubber cushions?? I just removed, rebuilt and re-installed my slicks..didn't see any rubber cushions.. Where are they and where do they mount, stick to??

Oh... looked around (web) and looks like they are only used on Bendix mags..Not Slicks.... Is that correct...??

It is my understanding the older model engines using Bendix S-200 magnetos use two rubber cushions in in the gear assembly on the accessory case where the magneto bolts to the case. A newer design uses cushions with wings that hold the cushions in place for easier installation. Called Lycoming and the guy there said he used a grease he called peanut butter grease. Anyone know what this peanut butter grease is? Lycoming guy mentioned he also used it to coat crank when slipping seal over crank.

Will just use some heavy grease to hold them in place.

At least in my Dad's shop, what he called peanut butter is better known as fuel lube.
