Thanks for that, is the timing sensor connection something that I could easily locate and attend to or, as a 'non techy' should I leave it to some-one with specialist knowledge ?
I'm off on holiday tomorrow so I won't be taking any action for a couple of weeks but, I do thank you for your advice this far.
O K, Matt,
Thanks' again for all your advice. I'll take a look for the sensors when I get back off holiday and let you know the outcome ?
