Hi Jack,

I posted a list of resources for interpreting Briggs data a few months ago in Tech Talk:

You might find some of it interesting - I think it is the first time a partial list of Briggs plant numbers has been posted on the internet. If you know the locations of any of the missing (closed before 2010) engine manufacturing plants, please post them so they can be added to the list.

There are more closed Briggs engine plants than open ones these days, and more seem to be closing. They now only make OHV and DOV engines in the US - all of the side valve models have been moved to Chongqing. They have announced that they are specialising in higher value activities in the US, which means only premium priced engines, and end-products such as ride-on mowers, snow blowers etc.
