Thanks for the above commentary and no, I don't mind at all. Harsh 'marking' doesn't bother me as long as it's fair, and this is all fair.
I invited editorial comment and if it is available to all then my errors are corrected as they should be.
I guess in my defense, I did a lot of the work afterhours and may have been a bit tired. Still, I had a lot of fun and managed to take a lot of informative photos - some a bit too informative

The literature I had didn't distinguish between the H30 and the H30A which is why I put the A in brackets. There is virtually nothing available for Kirby engines so I had to use what I could out of the Lauson and Tecumseh publications.
I'll try to get a new governor spring - on reflection, it is knackered

The upper limit screw was reset to where it was prior to disassembly, so I hope it is correct. I'll try to measure the engine speed sometime and yes, 1700rpm will be the idle speed.
The pdf has been uploaded.
Cheers,
Chris
