dclarke 4,046 #1 Posted December 10, 2017 (edited) A buddy was junking an old portable generator a while back and asked me if I wanted the motor/generator off of the engine. When I went to take it off I noticed this cover/kill switch over the spark plug, I've never seen one like this before so I took it off and put it in stock. Probably one more thing my kids will sell at the garage sale they're bound to have after I'm gone. lol...... Anybody see these back in the day?

diesel cowboy 263 #6 Posted December 10, 2017 Never seen one of those in person before only in the old Briggs microfiche at work. Its listed in the model 19 fiche as a shield assembly, spark plug part number 89742. Probably the same for most of the 8hp and up engines from that vintage 4 Share this post Link to post Share on other sites

I's been a while but I think it was a Briggs engine. Thanks for the info, Stewart. 1 Share this post Link to post Share on other sites
Sarge 3,464 #9 Posted December 10, 2017 Yep - certain old Briggs engines used those - I have only ever seen one at an engine show in one piece , great find . To think they would go to the trouble to make that from stamped tin in that detail shows the workmanship of that era - so lost on today's world of plastic and disposable junk .

Ed, you've got better eyes than I do, I sure didn't see any writing until I went and looked again. It's hard to read but I think it says "Licensed under Pat.
