It's hard to see in this image, but look closely at the triangular piece of sheet metal with a stud welded to it, right behind the prop: https://plus.google.com/photos/100843558075002483077/albums/5596558873691375105/5596568964201530370?banner=pwa&pid=5596568964201530370&oid=100843558075002483077 The triangle is bent offsetting it toward the center line and bolted to the front 2 cylinder studs. > I always thought it was stock J3, since it has a stock J3 cowl and engine > mount. > Bingelis does say #1 page 100 "As a rule the cowling is not attached to the > engine" > Maybe it works on this plane because there are only 6 attach points cowl to > firewall and 2 attach points to the engine block. > Anyway it has worked for almost 500 hours no problem.

One of the studs or the triangle pieces work-hardened and broke back in '09 but it's flown 150+ hours since then with no problems (unless it's broke since I sold it in '12). The holes in the cowl that slip over the studs are strengthened with a brass grommet, iirc.

I sure have to do something better and had been thinking of finding some rubber plugs and doing round holes but those covers look a lot more classic. are you flying that bird yet? wondering what size and pitch prop you have.
