Idling not stable?

This could due to many possibilities in which I'm still trying to figure out.
They are but not limited to:

• auto choke on carburetor is not 100% functioning
• power output is not stable
• faulty distributor
• not so reliable engine and gear mounting
• tuning not done properly

Possible solutions:

• have your trusted mechanic service the auto choke on the carburetor (less than RM30)
• replace your carburetor (more than RM1000)
• install voltage stabilizer (around RM100)
• setup proper grounding (costs unknown)
• replace distributor (around RM300)
• replace engine and gear mounting (around (RM600)
• have your trusted mechanic tune your engine on petrol mode
• have your NGV installer tune you engine on NGV mode
• readjust torque

I hope I didn't missed anything. If I find that I do, I'll update this entry
