2004 Suzuki Maroti Front Wheel Drive Manual 19858 miles

I am having Maruti 800 carburetor type vehicle, the current milage is 19858 purchased in 2004, the basic problem is that whenever the vehcile is started there is lot of vibratiion in the whole vehcile, specially the engine, whenever started in the morning or after long halts, I have contacted lot of mechanics/workshops but they are unable to solve the problem.

could you please advise me the reason and means of rectification on my email ID gclalwani@rediffmail.com
