Malikg115, thanks for the advice without reading all the topic thorughly, you should atleast read it first before advising to me. I had enough with visiting many cng mechanics and so called experts, but finlly on Mr. Bilal helped me to getting fix my car, and the way he did was really fantastic, I hv never seen in my life any engineer, remember so many brands of components name, wire colors, and their connections and then their proper and inproper functions, he really play on phone with these things, he was asking and guiding technicians, and he got the results according to his requirement.
I am glade that from that day my car is running quite well, there is no any problem now.
Logas, Mr. Bilal why dont you give some trainning sessions to all cng mechnics in Karachi, they badly need refresher cources, it will a great favour to them and to cng users, who are suffering with their illateracy.
Please think on the proposal I have requested for Karachi city.
