My friend's Mehran does not start on cold mornings.
Following has been done but still no big success.
1. Changed battery, no corrosion on terminals
2. new plugs/ point, plug's gap set to 0.7mm
3. checked ignition system thoroughly, checked plug wires etc, no leakage etc
4. starter motor serviced
5. spark timing adjustment
6. CNG tuning
7. ZIC oil used so its not that thick to offer noticeable starting/cranking friction
could anyone suggest what else it takes to start a 3 year old Mehran, only hiccups can be witnessed both on petrol & CNG
My conclusion, Mehran gets a weak starter motor by default, does not give good cranking effect, is it so ?
