Hi Theo, thanks for the explanation. Makes sense.
The codes are as follows:

I gave it a good test today and adjusted the revs and its running very nicely. It just needed a slight adjustment like you mentioned.
When thinking about this system today and it seems pretty smart.
1) You avoid people over priming and flooding the engine - common problem on junkyard mowers
2) When the system is functioning properly you can�t run the engine with the choke on, like lots of people do with Chonda�s . So many just need a good spark plug clean and they fire back to life.
To me this system seems fairly fool proof however I suppose someone would find a way to stuff the thing up.
It surprises me that other engines haven�t adapted this principle. Well they may have just not from what I have seen. More than happy to be told otherwise if I have missed something.
No doubt Grumpy will chime in with his thoughts on the design.
In my opinion I like it.
