On a 1923 Touring we heard, during a summer drive, a strange "Clung". A few minutes later the magneto stops working but on battery the car was running great and we finished the drive and the season on battery without any problem. During the last drive, two weeks ago, the slow speed band had to be adjusted several times. Last weekend I drained the oil and found some copper in the oil.
This made me taking the hoghead of and found the magneto problem. Took the engine out and take it apart. Look what I found.
Winter project just changed in a total overhaul.
Looks like your flywheel has been running too close to the magneto ring. Also the starter ring gear looks worn. Sorry that happened, but happy it was not worse.
Looks like the mag ring is original. If it is that is one item that should be replaced along with what ever else you find.
John and Norman,
I just finished the coils for the magneto coil ring.
The owner bought the car 3 years ago in Great- Britain. Till now we just done a tune up to make it run and usable.
By taking it apart we found a blocked Inside oil line and a lot of band material in the outside oil line intake. Connecting rods were X-groved but run with not enough oil and the X-groves are nearly gone. The cast iron pistons were 0.030 over but in good shape. We intended to keep them and just change the rings.
The part list we ordered this afternoon was for $1,500.- so a lot of parts will be changed.
