    I mistakenly fiddled with the tension spring of the weights ,so now my car timing is not aligning with the every step of advance or retard required by the car respectively. I fine tuned my car completely and tried every bit of the adjustment of distributor timing angle but still my car is not running properly. I did the research on internet and found that life would be much easy if I get the distributor tested and adjusted by the "Distributor tester".

    no workshop in Pakistan has a distributor curve tester, In your case, simply take it apart and see what you messed up, the distributor is assembled in one way only but you have to make sure you key it correctly on TDC when reinstalling the main shaft and the entire distributor to the engine.

    Are the weights loose in the distributor?

    I remember what changes I did in the distributor ,It was the spring of one weight ,1 weight was just a bit loose ,as the other 1 was firmly tight and I thought that it shldn't be that way ,so I bented up that spring and tightened up the weight and ever since than I am facing problems.
    Is it possible to get that spring new one from the spare parts shop?
    and what should be the gap(mm) of the coil contacts in the distributor (just for a recheck)?

    the one spring that is loose is supposed to be loose, its part of the advance graph. You cannot buy that spring separately as a part. however you can go to a shop that sells springs and show them your old one for a similar item, The weights should be free to pivot on their stalks and not flop around. They are two plastic pieces that are the actual bearings for the weights - dont lose or damage them.

    The main shaft of the unit needs to be greased with regular wheel bearing grease so that it can spin freely. The air gap should be about 1.00mm (let me check my notes - which are buried at home) and the reluctor should not damaged in any way - DO NOT use emery paper anywhere in the distributor.

    The vacuum breaker plate should move with a slight drag - its greased with silicone grease from the factory and you should not wash it with petrol etc.

    I will look for that spring in the market who sells springs ,I hope to find the exact alternate one.
    Everything in the distributor is in exact position and all that was changed was this spring that I altered.
    I will update as soon as I find that spring and replace it and then completely tune the car again.
    Sir ,the air gap between reluctor and the coil ,was that suppose to be 1mm? as I have set that at 0.7mm!
    No sir I havn't used emery paper anywhere ,even I don't rely on using that unless necessary.
    I even wanted to know that what would be the effect of the reluctor air gap? what will be the result if I decrease it and vice versa?

    0.7mm is too much,it should be inbetween 0.10mm to 0.40mm maximum.Air gap is directly affected on ignition timing,so proper gap is necessary to obtain accurate ignition timing.

    What do you suggest sir ,at what air gap should I adjust the reluctor?
    My car is suzuki alto vxr cng 2007 ,mileage is 1,45,000 kms.
    Engine is sealed ,only clutch plate and pressure plate was changed at 80,000 kms.
    I use my car on both fuels ,petrol and cng and after since this distributor problem my car is giving me the worst mileage.
    Petrol=6-8 kms per litre
    Cng=110-120 kms on 8 kg tank fill
