Guys: I started having intermittent and week spark with my 1949 Willys Jeepster with the Autolite IGW 4189 distributor. At first I thought it was the points, so I began a major tune-up, this Jeepster has been in a shop for 40 years. When changing the points, I noticed that the fiber insulator behind the point strip (insulating the point strip from the inside of the distributor body) crumbled as I reinserted the points and upon further investigation, I noticed that the fiber or rubber grommet insulating the point/condenser/coil wire stud was also coming apart. With my volt meter I now have 6 volts at the stud, but less than 1 volt at the points contact point with the points open. I think I can replace these parts easily, but I cannot find a source for the parts. Does any one have a parts source for the Autolite distributors or know of another fix? Thanks.
