I have had my carb refurbished by Bromyard a year ago but now i have to ride the clutch and do some higher revs when changing from stop to first and from first to second. The idle speed is very low but when looking in the haynes service manual there is no adjustment screw to increase the revs please could anyone give me any simple advice on this and if posible which screw/s i need to adjust-a diagram would be great Thankyou .

The idle screw on the 2E3 variants is pointing towards you just left of the oil tower, might have a plastic sheathe over it. Clockwise increases rev, Counter decreases. I've circled it in red.

Do not be too quick with thinking that increasing the idle speed solves the problem. When a carburettor has been performing correctly and the suddenly has a faltering hot idle speed it should tell you that there is a fault. Your fault is probably down to a bit of contamination withinand and simply increasing the hot idle speed with the adjusting screw only serves to mask the fault and does not remove the reason for the fault.
