I am using Nissan Sunny 1.0 LX with B12 engine, at CNG engine runs fine without any issues at Petrol at high speed things are OK but as push the pedal down the RPM first dies and then picks up again, really hurts me at slow speed because engine shuts off and again have to restart this happens only at petrol and during ramping RPM.
Carburetor issue cant find a place to correct the problem , let me know the right place to fix the issue??
