The poor performance of the engine can makes these faults to come up. we need to check from the fuel tank , check if the fuel contains impurities and specially water. If so this can come up when the tank gets empty and produce misfiring, splutter and jerks. So a check on the fuel filter will confirm this as it will be seen, if so remove and clean tank and change the filter. We then come to the carburetor as the fuel mixing is determined in this section. You need to have the carburetor removed and all ports washed and cleaned if there is traces of dirt or clogging noticed in the fuel chamber.

Secondly we need to check on the electrics. The spark intensity is most important .Remove the plug to check gap and condition of plugs. The black plug indication will confirm that the performance is bad whereas a fully fired plug without deposits must be the ideal view. Check the HT coil and the HT wires, if the intensity is bad the ignition system must be checked. DO NOT CHANGE any part without a confirmation--- trying with a replacement from another vehicle. Finally the LT trigger to the coils must be checked be it from the platinum points or an electronic ignition unit. The voltage of the trigger must be high to give the best HT output.

Finally check the Timing on the engine. Also check compression of engine since you experience starting fault.
