Ok My 2007 Dynasty 200 dx Hi Freq start was getting very weak so I called Miller and they were awesome! I talked to a guy who pretty much in so many words told me it sounded like points. So, I drank some beer which is required when you work on expensive stuff, and started taking my darling apart. I found the points, (they looked just like my 283 Chevy's but bigger) shined them up with some cloth, set the gap at.012, and my machine is like new!!! That is why I buy American. I love Miller, thank you.
