Valve covers, on motor and two I am working with.

There is a thread here or on .org where a guy welded in his own baffles in the Offy cover. It looked like it was made that way as he did an excellent job. I did the conversion thingy but that was before I bought my mig. The baffles would have been a good excuse to get it set up for aluminium. LOL Heck who knows it still might be come valve adjustment cause a guy can never have too many tools.
