Figure out the issue if the spark plugs are broken or clogged with wastage. If the plugs are broken then just fix those. If requires then replace them. Also, dirty or clogged plugs need to be cleaned. 

Once you are done fixing, do not forget to check one more time with the tester. Don’t forget to check the wiring and ignition coil as well. 

Problem 3: Operator Shifting Problem

If the fuel is any less, inspect the fuel primer bulb if there is any leakage or crack on it. Repair or replace it if required. Check the hose connections or terminals if they are working fine.
