    I found clumps of pitch, or tar, under the coil of my A 35. I want to replace the wires. The current wires were pressing up against the brass(?) tabs on the coil, but not soldered or connected beyond that. Is it best to do the same thing with new wires? Strip and press them up agains the tabs and pour in more….stuff? Where would I get more pitch?

    I believe the blacky tarry stuff was used to insulate the coil from the mag plate. I too cleaned it all off, only to be told later why it was there. I put down ‘Liquid insulation’ over the whole cavity area and my A-25 is working well. NABMD

    I am assuming you are replacing the plug wires also.Use 9mm wire and something like the pics show to hold them in place.You can then put some liquid tape on the connection.No real need to melt that pitch and re-use it,but if you do realize it puts off some dangerous vapors.

    I haven’t seen that glass tube/spring setup before. Interesting solution Tubs. How do you insulate your tack connection?

    I’ll brush on a couple coats of liquid tape on the
    magneto plate itself around the connection and
    leave the actual connection un-insulated. This
    makes service simple if you ever need to.

    Wow, I never would have thought of leaving that open like that. Makes great sense. Thanks!
