There are no workshop manuals avaliable online to the public (not genuine ones anyway) but you may be able to find a exploded parts diagram.
Thanks I've had an initial reply from the place I bought it and they are going to try and find an exploded diag of the carb which I hope I will get tomorrow so I can attack it on the weekend. Thanks for the manual link ADI but it's only the user manual - I really need the full shop manual and would like to get that anyway to have for future reference.
One thing I did get back from the dealer was that according to their shop, if the tank level is low, the fuel pump will never pump fuel up just by pulling the engine over, it's got to be running. Now that seems like a pretty darned big design flaw if you happen to want to start an engine with a low tank of fuel, it would explain my problem but I'm not sure it's a good "feature" - the Suzuki wasn't like that.
As suggested the nearest dealer is some distance away
but the selling dealer has offered to send out any bits that I find I need so full marks for that.
