My TR6 (Pi) is running a bit rich and doesn't like cold starts (once warm is fine).  Another problem is that when changing gear the car seems to miss a beat when I press the accelerator. Has anyone any idea on the most likely cause of these symptons? at the moment I suspect the metering unit is worn.

Cheers

Could be a lot of things, but eliminate the simple stuff first. Some of the symptoms you describe could be ignition related so I'd check all that out first including the timing and tappet clearances. If that's all ok check the enrichening lever on the MU - is it working as it should e.g. engaging and releasing fully? Check the fuel pressure at the MU - should be in the range 100 - 110psi. You say you're running rich, presumably because the plugs looks a bit sooty? On a PI that's not unusual as long as it's not excessive. Another thing to check is the operation of the throttle linkage and butterfly on each induction body - they need to be in synch with just the right amount of clearance to get smooth running in all conditions. If all that fails, then maybe the MU is getting a bit tired.

Good luck.

Check the "cold start" lever that increases the fuel output by about double. It is behind the metering unit and operated by the "choke" cable.  If not being pulled enough, it might give cold start problems; if it does not return to the "off" position when you push the choke in, it will run way too rich.

As James says, expect the plugs to look a bit black, they usually run rich at tickover. If you look at them straight after a good blast with no ticking over afterwards, they usually look better.
