Slick/ Unison 4200, 4300, 6200 and 6300 Series Magnetos

500 Hour Inspection $250.00 + Parts (Flat Rate)

Repair $100.00+ Parts (Hourly Rate)

Field Overhaul of Slick magnetos, because of the required parts to be changed, is not economical. Exchange is advised. Slick supplies new magnetos and does not rebuild core returns.

**After disassembly and assessment, if your magneto approaches exchange cost, we will return your mag and advise you to exchange. Disassembly and assessment is at no cost. **

A bad spark plug can fail the magneto and/or the ignition harness. Spark plug testers can fire a plug that the magneto will not fire. The use of an Ohm Meter as a primary check is advised.

Place one lead of your Ohm meter down the barrel of the plug, and place the other lead on the center electrode (make sure the electrode is clean).

A new resistor type plug should read between 800 and 1200 Ohms
Remove and replace any plug that reads 5000 Ohms or more.

Bad spark plugs caused this Magneto to fail in less than 100 hours of service since new. Notice how the spark burned through the Distributor Block as it reached ground. The resistance of the spark plugs were greater then what the Magneto could fire thus the spark took the path of least resistance to gound internally. The internal temperature was so hot the coil wedges where loose in the housing.

One bad spark plug can cause premature failure of the Magneto Coil and or the Ignition Harness. Remember most problems attributed to the Magneto are Spark Plug related.
