Besides 'too fast'.....can anyone guess what RPM this unlucky engine achieves?

The speed may be ok for that engine.
Many of the twins run at 1000 rpm.
- 6/1 GM90 Listeroid - Delco 33si Alternator
- Changfa R175 - Lease/Neville Alternator
- JiangDong R165 Air cooled - 2 kw
- Changfa S195 (Waiting for a project)

My twin is rated for 1000 rpm even though I run it at about 800.

That engine in the video didn't sound bad to me.
Metro 6/1 turning a ST 7.5 KW gen head
Changfa 1115 turning a ST 15 KW gen head
Ashwamegh 2/25
John Deere 110 TBL
New Holland TC 30

I thought at a couple points in the video it was turning excessively fast, over 1000. Maybe not.
