Thanks, Red Baron, that's it.
Edgar, I see the one you are speaking as well, diagonal not horizontal & much thinner in diameter and shorter in length than the one I was asking about.
I'm cleaning up the water pipe on a Roden 1/72 engine & I was curious as to what happened on the forward end of it. This particular kit doesn't have the magnetos, but I can use some from anther kit's spare engine.
