I helped out Gary Schultz, a Scott owner in California by finding a correct MC2 magneto for him. I had it rebuilt by Sean Hawker who did a superb job on it so it is just like new!
It was from a Douglas and I had had it on my shelf for years. Now I realize that the much later Lucas Magdyno he has on the bike has the larger taper fixing. The MC2 has a smaller taper and from memory is retained by a central 1/4″ BSF bolt. Can anyone help and sell a mag sprocket with a small center taper to save making one specially. I promise I will not add anything to the price, only I would cover carriage. If you prefer to deal and send directly, just contact me and I will give all contact details. His bike is a credit to us and we only need this item to get it correct. Kindest Regards to all Roger
