Missing/BackFiring/Joults on CNG

My car (khyber) is giving me missing probelms. I visited a CNG guy at national market Pindi and he said that a Hole in carburator should be made to inject the Gas directly into Carburator, and he did that and everything seemed perfect till evening , but when restarted me car in evening the probelm was there. Now someone has told me to change Spark Plugs. Guys What should I do? knowing that I have already spent money to tune up my car for tree to four times in week but probelms are not going away.I would aprreciate your help.

To replace the plugs,

1 - Check the plug gaping?
2 - When did you last changed the plugs? IF just do not need to change the plugs
3 - If you had kept CNG kit?
4 - When did you change the 'point'?
