Yes it does have the solid grooved wheel for the belts. I assumed it was something to do with decompression, but never having seen a startomatic in the flesh I wasn't sure.
Saw it for sale locally online, but unfortunately it looks like its in fairly bad shape. Just from looking at the photos online its, missing injection pump, push rods, cam end cover and looks quite rusty on the base. I'm still almost tempted.
