Managed to blow compressed air through the accelerator pump fuel discharge nozzle so refitted it. Blew through the rest of the jets while the carb was apart too just to make sure. Reassembled and it now revs properly.
Set of trim removal tools arrived in the post today so i could pop off the passengers door panel without resorting to using a screwdriver and possibly scratching the paint. Only £3.22 off ebay too.
Fitted the bonnet handle and was quite pleased that the bonnet still opened OK.
