Yep, correct on both. Briggs engines of that era are all 4-strokes.

Also, I'm trying to understand the pros and cons of powder coating vs non-powder coating. Would be great if someone could elaborate.
This thread, which I see you've posted on, has very good info on the drawbacks of powder coating SB45 components. https://www.outdoorking-forum.com.au/forum/ubbthreads.php?ubb=showflat&Number=59261

Rover used it after they took over manufacture, and it wasn't a success, in durability terms; whatever its production advantages may have been.
Powder coating is most durable on rounded forms; with no sharp edges, where it tends to crack and hold moisture underneath it. Which then becomes a corrosion hotspot...

The more i read on this forum the more tempted i am to restore it. I love the videos re engine, soleplate etc.

We'd like to encourage you in that; it's what we like to see, and help with!
