Or you could fit the distributor off an Uno FIRE - and never worry about points, dwell angle etc. again.
I thought you were going on about fuel problems, not ignition?
That first post was so awful I couldn't work out what was going on
Especially "i sent her out for more petrol hoping it that " - I imagine perhaps your wife trudging down the road carrying a petrol can? Are you feeling OK? With your experience of so many thousand posts, I'd have thought you could break it into paragraphs...?I think what you were saying is that the mixture was too lean. Did you find a problem with the vacuum advance capsule, or not? Does adjusting the mixture screw get you a yellow flame with the Colourtune scope (I presume that's what you're using?) or does the mixture screw have no real effect?

So how comes Uno's never had points then
An Uno's over here are harder to find than Pandas (or atleast in the east they are )

mixture screw do nothing
wife was sent out to get petrol
got fuel and ignition problems, there a dizzy like you say ( i think) on ebay and its only up the road, can i really fit this? http://cgi.ebay.co.uk/ws/eBayISAPI....m=120289196712&ssPageName=STRK:MEWA:IT&ih=002

Will be good if it does Dave. What is the plug with pins for? What plug in there then?

sorry 2 butt in
I've recently been twiddling my carb on a 1000s, colortune really not changing much at all between 2 turns left and right, possibly I get more of a burble sound out of the exhaust at the lean end, i've given a good blast of carb cleaner as per instructions.
m.o.t. was 0.1 CO but 225 ppm hc which was a bit high (or so he said)
mpg/power slightly better after after my marelli dizzy got a good strip down and clean, also dwell set to 51 from 58.
I can see the light blue 'further down' but also a fair amount of whiteish orange
in the mix. Is there something up with the carb here?
thanks, B.

Panda 4x4 86 on has also got the electronic gubbins on it that does away with the points, not sure about compatibilty with non electronic systems. And also dave's car is a 750 iirc as opposed to 999 that the 4x4 panda and the unos are. I'm not sure but as long as the electronic side of it is compatible the engine size difference shouldn't really matter in theory.

I'll have a look at lou's engine tomorrow morning and see if the electronic side of the dizzy is self contained or relies on something else on the cars wiring.

oh just remebered. Changed an engine in a 1400 peugeot 205yuck. This engine uses the electronic ducelier dizzy which is virtually identical to the one that pandas and uno's use. and the plug that jon asked about connects to the wiring harness and isn't self contained so don't think an electronic one would work on your motor dave

Dave panda carbs have a common problem on the mixture screw, remove it and see if the point on the screw has gone blunt. If it's been messed about with in the past someone has probably tightened it and blunted the screw. If that's the case you will never be able to set the mixture correctly. Happend on both sisleys and replaced the carbs with new ones.
Condensors can also be a problem but if they are knackered the engine wont run so it won't be that.
To remove the plate on the dizzy remove the screws and pull out there is a central clip but cant remember if that has to be removed or just comes out with the plate. I would think that the points will be in stock so should be obtained easilly.
The 4x4 ign unit is self contained and connects to the coil.
The 750 & 750 van from 86-92 has a Marelli dizzy and 2 deg BTDC n/v
The 750 young from 91-93 has either a Marelli or Ducellier dizzy and is 5 deg BTDC n/v
All other panda's except the 903 has a setting of either 2 deg BTDC n/v or 15 deg BTDC with vacum which is the exact same setting (if you set your dizzy to 2 deg with no vacum and connect the vacum pipe it will go to 15 deg)
So if your 750 engine is set at 2 deg n/v or 15 deg v I think you can use the 4x4 dizzy with the electronic ign. The theory sounds OK but obviously don't know in practise.
I bought a 4x4 Dizzy with electronic module on ebay thinking they were all the same, but when fitting it after about 2 min the car died, then noticed that the numbers were different I have tried several others with the different numbers and the same thing happens after 2 min the engine dies.....why? I have no idea. All the other units I have tried with the same numbers work perfectly.

my tyre has come so i can go out now. so i get these bits an see what happens an also check this screw
Alan's spot on with his list of dizzy's. I've cheked my workshop manual and the 750 and 1000 pandas use the same dizzy with the same settings. The 4x4 uses a slightly different dizzy but with the same settings and ignition curve.
The 750 young is a 769cc version of the 903cc engine and I havn't seen one in the UK.

So it is, only just looked again and noticed
also noticed that they have the exact same power output

no one warned me the price for points be a sit down job they are saome sort of kit and was £15 twice as much as dizzy cap an rotor arm together. i thyink i got a binding brake now too

oh dear, these problems are all looking verrrry familiar right now. I have had brake and carb problems for the MOT too. My car was running really rich apparantly so I have had to adjust the mixture, but it doesnt make the difference I had hoped to the running. Perhaps the mixture screw has been blunted as alan has said on mine also.
The MOT retest is tomorrow, so I will soon find out if I have weakened the mixture adequately.
Hope you get your 750 bk on track anyway. Only thing that keeps me going is the end result of driving the car :slayer:

i jacked it up an its got slightly sticky pasenger front brake, that be why i only could do 20mph on way back from town earlier then
Prob cause it's not been used much OR the hoses are starting to fail not allowing the fluid to release pressure. Try loostening Dave buy pushing the caliper in and pumping out a few times. If you find the seals are good and you can't push the caliper in I would say it's def the hoses at fault.
As Alan says above, I think it's probably the rubber pipe on the way out, perishing on the inside, and not letting the pressure out.
And the Points sound about the correct price. May seem alot of what they are, but when fitted, my word the ole Girl will come alive!
