Hey biged,
I found that info this morning. The supplier I recommend is Branson Enterprises, Ph # 815-633-4262, in Loves Park, IL. They specialize in mags, carbs, and parts for them. I wrote some &#039;Tech Tips&#039; articles on this, The Ensign carb was the March/April 1998 and the May/June 1998 issue. The American Bosch U4 Edition 3 Mag was the Sept/Oct 1998 and the Nov/Dec 1998 issue. You might want to check with Chris Losey to see if these back issues are still available. They give step by step details on rebuilding these units. I hope this helps you! Later, Andy
