Hi Oldbloke, This is certainly an Engineering masterpiece! However, you seem to have the HS6 carb set up rather than the HIF6's I have on the late P6. Thanks for posting this one. Thomas

Just out of couriosity: I have been working on my throttle linkage over the past few days to eliminate the present play in order to be able to adjust the kick down cable properly. I put the proper rubber bush in the central bracket (there was none before) and managed to obtain close to zero...

Respect Demetris, looks like you were right! After re-installing the carb with the replaced cold starter unit O-ring, everything is back in order! All 8 cylinders are firing again. Apparently, the mixture was overrich and thus not igniting on the RH carb side. A little finetuning is still...

@ Demetris: Took the carb off again today and dismantled it completely including the cold start device: - again plenty of petrol inside the carb - there is 1 O-ring on the cold start device but it had a very loose fit, so I wonder if that was really sealing well. Fitted a new one. - adjusted...

I tested the carb and found: - a spray of petrol is visible when looking down the RH carb with the engine revving - looks the same as the spray on the other side's carb. - additionally sprayed starter spray into the air intake - no change! - the plugs of the non-firing cylinders look wet - still...

Checked the valley gasket and the servo/pipe: no leaks whatsoever. Still suspecting the carb: what causes the complete refusal to deliver pertrol?? Thomas

It's the RH carb as Harvey said. I removed the carb (HIF 6) and took it apart, but I could not find any obvious problem. The float chamber contains petrol and is absolutely clean. The needle valve could move freely. I used compressed air and blew through every bore, everything seems to be...

Hello, I have the problem that all over sudden the engine started to run rough such as if one or more cylinders were not firing. The following was tested: - changed all spark plugs - every cylinder gives a spark (when checked with an Accuspark tester) - changed the dizzy cap and the rotor -...

Well, the looks are okay but the question is whether or not the cable is long enough or not. The original one measures approx. 125 cm on the outer cable plus 10 cm on the inner. Thomas

Thanks for this information. It was quite helpful. The cable is out now but only to find out that my usual supplier (JRW) is out of stock at the moment. I need the single cable version for HIF6 carbs. Has anybody got an alternative source for one? Thanks Thomas

Hi Ron, I have to replace my Choke cable, and I was trying to review the previous thread you mentioned above. Unfortunately it can't be opened. Any Suggestion how and where this piece can be accessed? Thanks. Thomas

Thanks guys, that's what I thought. What puzzles me is the fact that I lost about 30° duration on both, inlet and exhaust, without noticeable wear on the lobes. The lobe lift of about 6,25mm also seems to be right on spec. But maybe, the camshaft was never made to what the workshop manual...

Hello, I dug myself a little deeper into this. Removed the inlet manifold and checked the condition of the camshaft lobes and the surface of the lifters. To me, they all look alright. Measured the cam lift directly of the lobes on serveral cams, and all read about 6.25 mm. Here is what the...

Just found the information that the standard rocker ratio is 1 : 1,6. This would give my valves a lift of almost exactly 10,0 mm which is to spec! Why then should I change the camshaft at all? Thomas

Have now taken lift readings directly off the pushrods: both inlet and exhaust have about 0.250" (6.35 mm). I have been reading that the standard cam lift is 0.390" (9.9 mm) but I 'm not sure if this means the lift of the cam lobe, or the true lift of the valve which would be bigger due to the...
