No longer need this one. I believe its an M, the bolt hole pattern is 2″ X 1-1/2″. One of the bolt holes is rounded out and needs repaired, The magnet needs charged which is how I bought it. I believe everything is there. There seems to be a lot of interest in this so I want every one to know that it has no spark, It for sure needs the magnet charged. I want to be as honest as I can about it. The item “Webster M Magneto for Hit & Miss Engine” is in sale since Friday, September 22, 2017.
