suzuki zen 2001,carburator type engine ,65000 kms done,engine misfires during start ,mileage is very low does adjusting the timing belt or replacing the timing belt solve the misfiring and mileage problem pls advice

if its misfiring when your starting the car its not your timing or the belt don't touch that at all check your spark plugd and wires if the are good buy either a carb cleaner or fuel injector cleaner it should help

try replaceing the plugs ,cap and rotor.if applicable,just plugs n wires,

you must first check comprestion on the cylinders check spec. for you car and see if its within spec if not then its going to be timming but before you do dat check easy things first check if you have spark, check coils dependind on your car . any queastions just reply back and ill get back at you k bro

is the check engine light on? a scan tool will tell u which cylinder is missing
