|Preventative Maintenance and Troubleshooting
General Engine Maintenance-
Keep engine clean-
By doing this you are helping the cooling system by keeping cooling fins free of debris.
Check oil level and condition-
Crankcase oil should be checked and changed periodically, if engine oil is low add some. Do not run engine with oil level above or below oil line..
If to low- well you guessed it engine could seize up not enough lubrication, sealing, and cooling
If too high- oil could splash up past rings and get into combustion chamber
When to change oil-
Usually it is specified by the manufacturer, but 40-50 hours of use is a good guideline.
If oil is dirty- oil will not take contaminants away from engine parts, and will not protect engine parts.
To Change the oil- drain(Let drain for 5 minutes)- Check manual for amount to be refilled, fill and Check with dipstick.
Check Gasoline- Make sure gasoline is fresh if possible, If stored in gas can try and make sure can is full to prevent condensation-
Condensation- Forms in partially filled containers because of temperature changes, during the day the air above the fuel may become warm and hold more moisture, at night this air cools and releases the water vapor on inside of can, this can mix with the fuel in the can.
Storage- Use fuel stabilizers when storing fuel for extended periods- this will prevent fuel from oxidizing, or degrading.
Air cleaner service- Make sure air cleaner is clean, if it is not it could make engine hard to start, and loss of power, along with spark plug fouling.
Systematic troubleshooting- Make sure that one component works after another until problem is located.
1. Check the easiest thing first. Achims razer
-Example- if engine will not start don’t start tearing apart carburetor before you check to see if there is fuel in the tank.
2. Verify fundamental operating requirements.
-In order to run your engine needs five fundamental things
A. Proper carburetion- clean fresh fuel must be delivered in the correct time and amount to the combustion chamber.
B. Correct Ignition system operation- Strong spark which can jump gap of spark plug at correct time.
C. Adequate Lubrication- The proper amount of quality lubricating oil must be present.
D. Sufficient cooling- Engine must be able to cool itself.
E. Proper compression- A compression reading of around 25-35 is required for efficient operation and sufficient power.
