Early Jaguar Auto Enrichment Device

I had bad starting problem and running until warm on a 2 year old XJ6 I had while working in Southern Germany.

I constantly looked like the third starting carb. Tried lots of things over some time but could not get 'good starting and running'. I even put a new unit on. I ended up taking the third carb off and blanking the hole.

The car would then start no problem in minus 10 deg by fanning the throttle when starting it. Once it started it needed just a little help fanning the throttle for the first minute to pull away. I never bothered to put it back on. It made not difference in normal temperatures.

Bad form following your own posts etc.

I've just thought. I didn't take the starter carb off. The final fix was the fuel line blanked off. Cab in place with the electrics disconnected.

It was like that when I PXed it for the next car. (1979?)

I was thinking the same. It's amazing he got that flight at all.

He'd be fine, as long as his passport states his ID as S.U.Weller.

Santa got priority but still hasn't recovered from missing a nights sleep.

I can get it to start easily enough but it won't idle happily until it's up to temp and is a bit lumpy pulling away. The AED on the early type is slightly different and cruder than the later 420/Mk10/XJ6 type.

The local car breakers (who does a sideline in stashing old Jags) has another solenoid for a score. Fortunately it's a thirty second swap so I can check it there.

Just chucking ideas in the pot!

As far as I remember it has two actions. One for cold starting and a second for warm up.

If your car started and ran without the starting carb it must have been running ridiculously rich. Because it's the same as saying a car fitted with SUs with a manual choke wouldn't need the choke used on cold days.

Hence having to fan the throttle when hitting the starter. No it wasn't running rich. It was spot on with very good MPG.

Pfft. My old 4.2 LWB XJ6 had starship mileage and correspondingly timeworn components. The 'choke' didn't work worth a damn, but a good footful of throttle and providing the truck battery had enough oomph in it, it would go after 30 seconds of churning and farting.

I never bettered 14mpg from it, the worst was 9mpg in cold weather.
