SLICK MAGNETOS
**NOT COST EFFECTIVE TO OVERHAUL**
In our opinion Slick Magnetos are NOT economical to overhaul. Champion Aerospace has a list of parts which MUST be changed to qualify as OVERHAULED. The cost of these parts far exceed the cost of an exchange (NEW) magneto.
The following are Manditory Parts that must be changed to qualify as Overhaul.
