Thanks for your reply, as i purchased the car almost 6 months back and after that i drive mostly on petrol and after carb service i am 100% driving on petrol.
Air filter : Already changed with Guard
Spark Plug: Also Change purchase from Fairsale shop in plaza and he give me copper single tip brand name Champion made in USA
Starting: half self start without any problem (Mashallah)
Plug wire: when i was removing the plug wire from the distributor cap the wire came out and clip remain inside than i take the clip out and again punch the clip over the wire for all three wire on distributor side. Now i am thinking to remove the wire from coil and see if the clip is loose or fit.
is it possible i an ask the electrician to check the plug wire & Coil resistance? as i dont have the tools for that purpose.
Also the previous owner use 13 inch alloy with 13/70/170 tires i believe is it advisable to move back to 12 inch for fuel economy?
