I saw your earlier post about air bleeds.
"Greg" sent this to me:
"Some Scheblers have an air bleed hole on the side. These would be matched to
a venturi with no slot.
Some Scheblers have no air bleed hole. These need the venturi with a small
slot milled in them.
The purpose of this is to provide air for the idle circuit (I think). So,
before you plug the hole check out your venturi."
Seems right, what do you think? My old DLX-10 has both , so I ran a 2/56 plug tap into the hole, kissed with a c-sink and blocked the hole with a regular flathead, v-bottom screw.
We`ll see how it works, but I am still messing with the magneto.
