I had a "Visitor Message" this morning from someone called "hedman" asking for this Doco.

That message has been devoured by Cyber Space, but here is the Doco as requested.

 

Hay Grant - what an excellent write up... my car is running well but starting can be a few wirls... then a few cylinders fire up, then all. and it idles nicely.
So I will go though this and see if anything is a miss... cheers

 

Many thanks, Grant!

 

This will come in hand soon once I get what I have a part back together. Thanks.

​​​​Thanks!

Hi,

I read from the notes that you have removed the AAV. Can I know what needs to be done if we want to remove the AAV? I read that there are rebuild kits available, but if we have a choice to remove it I think it would be better. I have also read somewhere someone hooked up a sort of manual choke kit, but I am not sure that is the best idea.

Appreciate if you can advise.
Thanks.

 

Grant,

Further to our PM's, I've QUOTED peckhs 'invisible' post so you should be able to see it here ......

Thanks peckhs,

Thanks to GGG I can now see your ask. I was not ignoring you, just could not see your reply/ask.
It was "hidden" for some strange cyber world unknown.

These 2 attachments say it all.

 

Thank you very much GGG and Grant.
Loads to learn about the XJS. Although I will probably find it as fulfilling as when I was learning about my Esprit!
And Grant, I have printed out all your stickies! Gonna go through them especially the post purchase suggestions, although I may not be able to do all immediately.
Cheers!

 

Good afternoon Grant,
I am giving the Daimler an oil and oil filter change, fuel filter (went to a glass bowl retro unit), Air filter, etc. and wondered if you have a worksheet for the carb tune up? I have 4 x colour tunes, a venturi intake guage, and the Jaguar V12 service manual, so I am well set up to do the work it is the order of tasks that is in question. I have been trawling the web this afternoon to ascertain if the mixture comes first or the idle setting?
Proposed order:
a.Set timing statically;
b.Set mixture using colour tune;
c. Set idle using venturi guage to balance the 4 carbs as per the manual.
d. Take car for a spin as per the HE tune up procedure.
Any comments on the logic?
Cheers Chris

Chris,

Only ever tuned one of those in all the years.

Now I am thinking, "where is that Stromberg Jet Tool", as if the brain did not already have enough to do?

My memory, and the same applies with the 6cyl XK with SU's.

Set the timing static 10deg BTDC will be close as hell.

Warm it up, 3 beers usually.

Adjust the idle.
Adjust the mixture.
Adjust the idle again.

Go for a drive, so the "Drive Timing" can be set.

Have a beer or 2 when back home.

Reset the idle if needed, 95% do.
"Tickle the mixture" to find that sweet spot.
Reset the idle again if needed.

If drive timing is not possible, "tickle" the timing, that Sweet Spot will be heard, call it done.

I have never used any fancy gauges, nevevr had them way back then. A hose in the ear, and balance the "hiss" has always work for balance and idle. TIME CONSUMING, hell yes.

Mixture is a 6th sense, gets better as you age, and again, the Sweet Spot is felt and heard.

Having the carbies mechanically separated is paramount. The connecting rods can be tightened after the setting is done.

Strombergs are a pain, but doable with time. SU's are simpler in MY opinion.
