Hi Mark, don't know if this will be any help, but at my last MOT my emmissions were high, the tester kindly adjusted these as I couldn't find the screw,it was in what was effectively the mounting flange for the carb,quite well hidden if you don't know where to look and certainly not obvious. Regards Bill

To: [email protected] I have looked at a pic of the TLDM, very similar but the top of the carb is not round. I will keep looking at pretty pics of carbs on the web, I am sure that I shall stumble across the right one eventually.... I hope.

Are the barrels square or round? Mine has a thumbwheel for adjusting the idle and that is a TLDM carb used on the later XR2s Russell On 24 Oct, 09:53, Mark Miles <[email protected]> wrote: > This seems to be the problem I am having with finding a diagram for the carb > as > it is an '86 model cvh so I am guessing that the carb is probably an > aftermarket > unit or grafted on from a later engine.
