This motor ran fine for 2 yrs but then started cutting out after starting. The only mechanic in my area who knows anything about merc motors of this era says it is the points and they are no longer fileable. Coil problem has been ruled out. Have been unable to locate dist cap in my area. Any idea if he is correct and if so where I might locate one. I have this motor on a 56 Feathercraft. Nice set up. I would hate to scrap the motor for this issue.
