Fuel and air mixture screw on carburetor "flew off", I fortunately found it.
"Silent shaft" noise is present indicating a loose bearing after almost 12 years of use.
Maintenance is very easy, parts have to be sourced out carefully.
Mileage is about 4.5km/ltr city driving and 6.5km/ltr on long drives out of town.
Had the same problem with mine where the air fuel screw fell off and engine won't run smooth. Luckily found it again cause finding a replacement screw is not easy. Mechanic put a dab of glue on it so it won't fall next time. Very useful vehicle and gives owner pride of ownership even after many years of usage. A bit underpowered for the weight of vehicle, but very reliable engine compared with the v6 ones where crankcase pulley bolt is a known problem. Would recommend friends to buy this particular model.
