I've found the triple choke design frightens some of them.
The PMO's have a lot of DCOE parts to them, esp jets, but even that worries most.

It was this that forced me into DIY tuning once we had 'lost' Bob Watson.

Richard recommended Tuthill or Neil Bainbridge. However, neither are in Switzerland unfortunately. Maybe I'll bring a few spanners and my vaccuum tool to Switzerland next time i'm in the UK and do it myself.

I have had 40 PMO in my targa for 7 years. It sounds to be a known issue that if you leave the car sit for, let's say, a week or more, it will need at least 10 seconds of fuel pump action to fill them up before you can crank the engine.
I don't think that's a real problem but you have to know it before killing you battery and starter....
