My Mehran 2004 does not start on petrol when cold. It starts on cng. Also stalls on petrol when engine is not fully warmed up. After the engine is at normal temprature the problem goes away.
Dunt accelerate when statring the vehicle ... Adjust CNG n Race setting ..Clean up Air-filter regularly
Had similar issue. Tappet Adjustment helped. Mechanic commented: Tappets were tight.
