I have recently bought a GT6 Mk3 (1971). It appears to be fitted with the age appropriate CDSE carbs and the 311749 early Mk3 inlet manifold but the engine has been replaced with a later engine, KE21904HE, and the crankcase breather valve is no longer fitted. With ignition timing, tappets and plug gaps all set correctly, the engine runs with the front three cylinders far too rich, while the back three cylinders are running at the correct mixture. Can the mixture be made more lean on the front carburetter or is there something possibly wrong with the temperature compensator or throttle by-pass, please ? The Insulator and gaskets between carb and manifold have an internal slot , presumably part of the throttle by pass, which the gasket does not appear to fully seal from atmosphere, is this correct ? I have no experience of Strombergs, would fitting an earlier CD set without emissions control be possible and make life easier, or even an SU conversion ? If I have to have the carbs reconditioned, is there a recommended firm to contact ? All suggestions gratefully received.

I have just bought a "restored" GT6 Mk3 and am finding some horrors like greased trunnions, "slotted" wishbone holes and front tyres fouling the bulkhead on lock - all despite an advisory free MOT cert. I have no previous experience of Triumph foibles and desperately need guidance from those with the knowledge. The car is on 175/70R13 Tyres, in what combination of circumstances could these foul the bulkhead ? The road wheels look to be standard with no spacers but are not marked as 4.5J. The coil springs appear to be new but as I have no build history I do not know if they are standard height or lowered versions. Could spacers or collets have been omitted from the coil spring/shocker assemblies when they were rebuilt ? Any suggestions will be avidly pursued.

Hi, I am Nick and have just bought a 1971 GT6 Mk3. This is the first Triumph I have owned in 50 years and so my knowledge of Triumph and the GT6 is absolutely minimal. I am now accumulating a string of questions to ask the experts. Please bear with a Newbie if the questions have been answered many times before. I understand that there is a monthly club meet at The Crown, Shillington, so I hope to meet a few of you there.
