Mostly the flywheel. Being the all cast one vs the one with plastic fins. And strangely enough, the intake manifold. It is much larger than the other one as well.

Decided to go out and measure those intakes.
15hp 1.25" diameter. (unrelated note, I think that fuel filter is backwards and the wrong one for fuel pump )
18hp 1.5" diameter.
Finished project.

So I got a bathroom scale and measure them. The 15hp Craftsman is 94.6LBS with oil. The black 18HP was 95.8 with oil. I would have thought it was much more than that. I just struggle with the black engine. I can manhandle the red one? 1.2 lbs seems so much more. Who knows.

Oppys are weird about intake manifolds, they went through several iterations. They were split like onan ones up until the mid 80s, where they went to a solid cast iron one, then it seems somewhere in the mid 90s they went to a solid cast aluminium one. I've had all three, they're functionally identical.
Actually I'm not sure if they ever went to cast aluminum manifolds on horizontal oppys. I've seen some of the late year horizontal oppys and don't recall them having aluminum intakes. They had split and solid cast iron ones for sure though, as i had both of those.

Yeah, this is the original intake for the points oppy that was originally on Kal. It's a split, I ended up using it on the hotrod craftsman phase.
Then the cast iron one from the 85-86 murray engine. Original to this engine.
Not sure if Red is aluminum or not, I think it may be cast iron too.

Simple little ride. First part of the video, you can sear how well that 18HP runs. Very happy with the engine.
Few things to work on post ride: - Tie-rod ends need tightened back up.. Need some locktite. - Bracing plate on the side dash came loose. - The transaxle appears to have started leaking. Need to figure where. May have to pull it. Not bad yet, but is there.
