The idle, and when running on slow speed is sometimes very lumpy. This makes it difficult to adjust the ignition and it's also very uncomfortable. Could it just be carburetter adjustment. The exhaust also produces small "poff" all the time. The car is equipped with a pertronix electronic ignitior.

It could be an air leak on the inlet side somewhere. Try spraying wd40 or trickling thin oil around the inlet manifold and carbs. If there is a leak the oil should be sucked in an you'll see smoke in the exhaust.
Alternatively, the 'poff' might be due to a worn or sticking valve. Does the engine otherwise run ok?
Could just be worn carbs. New needles and jets might do the trick.

I had a 2000TC for 10 years & it was a different car when it was set up properly to when it wasn't. Just balancing the carbs often worked wonders, but a full tune (incl. mixture & timing) really made a difference.
TC's are well known to go off tune rapidly. I found that after a couple of months of regular driving mine lost its edge.

I've just had the inlet manifold out, and the engines behavior has'nt changed after this operation, therefore I guess that there's no leak in the inlet manifold. But I've not checked the carburetters. Otherwise the engine runs very well, and I am actually a little impressed of the engines performance, taken in consideration that this is a 35 year old four sylinder engine. Does anybody know the accurate BHP in this car. I've seen everything between 107 and 114 bhp in different handbooks and car books?

Hello Petter,
according to my "car technical details" (a pocket-sized booklet containing all the facts and figures required by Rover salesmen) dated October 1968 the maximum b.h.p. (gross) for the 10:1 comp. ratio is 124 at 5500 rpm and for the 9:1 comp. ratio is 117 at 5500 rpm.
Hope this helps.
Regards, John.
