Citroen AX tuning

Hi All,

I've finished converting my Citroen AX 1100 petrol with Solex carb to LPG and she runs smashing on LPG. I do however have a small problem when running on petrol which was there before the LPG conversion. The car seems to need a lot of choke until she is quite warm. The car then runs reasonably well until you go round a sharp roundabout/bend when the car seems to lose power before she then pulls away again. I seem to be able to run fine if I give the car a little choke or give the car plenty of throttle going into the corner.

I have adjusted the car with an exhaust gas analyser and am getting 0.8-1.2% co2 at idle. I have also checked the timing and am getting 8 degrees which is spot on. I tried to adjust the carb by setting idle and then adjusting the mixture screw for fastest idle but I seem to be able to unscrew all the way and never reach a peak speed.

I notice when starting up the exhaust is quite sooty on petrol.

I think the carb could be at fault here any advice on a cure. Perhaps a strip down and clean? The car has done about 60k miles.

Yes ... it did on my axgt. Several times during the past few years, i have been accelerating wildly round a left hand bend when its suddenly suffered fuel starvation. And on mine it won't clear ... it will idle ok (the idle mixture comes from a different part of the twin choke solex carb) ... but acceleration is a no no. So, off with the k and n filter, unscrew the primary emulsion jet and lift out with a cocktail stick, then unscrew the primary running jet and lift this out with the stick as well. Next, remove the cap off a bottle of windolene window cleaner, stuff the pipe end deep down into the carb ... and pump the bugger dry. (Obviously spraying the fuel into a receiver .... NOT ONTO THE HOT MANIFOLD!!!!) Works well ... and assuming your single choke carb has a similar jet arrangement it should work for you to. Watch you don't create any nicks or burrs on the jets though!!!

P.s: The twin choke axgt can be driven home when the primary choke is playing up ... just by using the secondary choke ... e.g: more than 3/4 throttle, which is quite "wild".

Thanks for the tip. I'll give it a try. I would have taken the thing to pieces to do it.

Tends to be very messy, and also blocks the jets up.

Kinda hard to perch over the engine too!
