Yeah well I had the version with the 2 extra pods to adjust fuel and timing, very rare, but had to sell it, as it was not what I wanted. Bought then a basic version with no option or warning light but in real MINT condition, so again was not what I wanted. After all this time I'm glad I found what I was looking for.

And yes, as you said they can be a real pain in the arse if they don't work straight on.
