not sure if anyone has come across this, but it seems like an interesting thing to watch and follow

 

Bookmarked to watch later. Knowing this would've saved me THOUSANDS on my first XJS.

 

Hi daverb

Interesting Video but I wonder if that engine can run as smooth as this about 1/3 down page: 40 (link to that page and Video below)

Coin Balancing Test Video on 'Cherry Blossom' my V12 XJS

 

I have seen that, wish I could get mine running that smooth

 

Hi daverb

This is another Coin Balance Video that I did a bit earlier but since the Coin was between the Grooves of the Inlet Manifold, I thought that was Cheating a bit, so I did it again in the Video that you have just been watching

Though nothing to to with the engine tuning skills I've never had, as this was after I pulled it all apart to Change the Plugs

It was all down to luck as well as some help from the 'Jaguar Gods' so I'm as surprised as you were

I've lost money trying the coin test, even with a chunky coin.
How do you get an engine to run that smoothly? Even with all the work done on mine, there's still some vibrations at the lights.
