I had two digits transposed in the original post for this engine. 170542 instead of 170452.
4 Horizontal, Flow Jet, Belt drive ... well horizontal for sure
5 Gear reduction 6:1
9 Mechanical starter

Thinking about putting this engine on the sand muller.
Say we run the engine a 2000 RPM
The 6:1 output is 333 RPM
A 10:1 right angle gearbox would result in 33 RPM which is about right IIRC. Need to look.
But I don't see an affordable gearbox.
So a mule drive would do the right angle thing. Maybe some of the reduction too.
Need to look back at the earlier work I did on the muller in the Foundry blog.
Not seeing much advantage as complexity is similar.
Well at least I got the model number figured out.
It a gas engine is the choice a vertical shaft engine would be the way to go even if it needs one more belt. Not fond of using a mule drive. And 8 HP is over kill. There is a small electric start mower in the junk that might be a better choice.
