When I go to auctions, there is usually a pile of old Briggs aluminum condenser and points lawnmower engines sitting in one corner. Usually they are a gift to the scrapper who buys them for pennies.
One time this past summer, I bought the pile since there were two nice Clintons in the mix that didn't deserve scrap. I see arrowheads and I see treasures, even if they were toast.
I have since shredded the vertical Briggs engines and sent the broken rods, twisted cranks, and scored bores to scrap. I didn't think to ask if anyone wanted them. Sorry about that.
I found these pictures while I was shuffling images of the forklift project a few minutes ago.
This was a unique variant the Briggs starter clutch (square drive) that you always see. I guess it must have went to some special starter setup, I didn't think the impulse starters used this style drive? I've sold a fair share of impulse parts and complete units but I thought they used the square clutch
Someone must have gotten ticked at a starter along the way on another model. They must have tapped the shaft the clutch spins on, since I found a rope starter cup threaded on and half the clutch holding the flywheel on. I'd never seen that before.
I had this style condenser on the old aluminum ignition kits. I guess this predates the spring style that we all are familiar with.
