Slow and reverse will not work on our nija four wheeler

If you have a Honda Rubicon, you must place the transmission in Neutral, then pull in Left Hand brake and push down Reverse knob that will remove the reverse lockout and allow you to shift it into reverse. If that doesn't work your reverse lockout knob might be defective or out of adjustment. The adjuster, depending on which model you have, will be on one end of the reverse lockout cable.

is the reverse lockout cable working right?

every four wheeler I've ever worked on has the ignition timing fixed and controlled by the CDI. Mechanical timing usually invovles lining up the T on the flywheel with a mark on the cam shaft. you'll need a service manual for more specifics.

is it a 12v or 6v four wheeler?

make sure the carbeurator's low jet is working properly and not clogged

Dead battery or solenoid

check the battery with a multimeter and see if its showing 12 volts or more, if it is showing volts but not 12 or more then put it on the charger for about 8 hours, then check the battery again if it still hasn't went up check the voltage of the charger with the multimeter and make sure that the charger is putting out 13.8 volts or more, iif it isn't then you need a new charger, if it is then you need a new battery

try backing out your fuel/air mixture screw 1/2 a turn. This should be 3 turns out from seat.
