Hahaha, what kind of mechanics they are.
@sbdanish911, search this topic what ever your problem is, you will find lots of information.
I think your carburetor also required a full service, bcz its not looking good in pictures. Go checked it by some professional.
This 20 year old car can perform better than todays cultus, you just need to revert every thing back to stock. And beware of such so called mechanics.
Keep in mind, every part have some mean in your car, company is not ----- MAD.
