A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured) or the flywheel. These have the largest radius rotating at crankshaft speed and therefore are the place where marks at one degree intervals will be farthest apart.
Signs Your Ignition Timing Is Off

Some things to look out for: Engine knocking: Engine knocking occurs when the air-fuel mixture is ignited too soon in the cylinder. The mixture then pushes against pistons that are still trying to compress the mixture. This causes loud pinging sounds to come from the engine.

When any changes are made to the engine of a car, the ignition timing is adjusted accordingly. If not, you could experience several problems with your engine with improper ignition timing like knocking, hard to start, increase fuel usage, overheating, and reduced power.
Most engines set ignition timing somewhere between zero and 20 degrees before top dead center. This is called base timing. When set, the ignition system and engine are timed so the fuel in a cylinder is at its peak burn just as the piston compresses the fuel vapors into the smallest amount of space.
Most engines have between 5-20 degrees of ignition advance at idle. This is referred to as initial timing.
The acceptable operating speed range is 1800 to 3600 RPM. Idle speed is 1750 RPM. The manufacturer of the equipment on which the engine is used, specifies the top governed no load speed at which the engine may be operated. DO NOT EXCEED this speed.
Most engines have between 5-20 degrees of ignition advance at idle. This is referred to as initial timing.
Rev the engine past the point where your mechanical advance is fully engaged. (Usually, 3,000 – 3,500 rpm will do it.) Watch the timing mark on the harmonic balancer using the timing light.

Every time i use the mower i have to recharge it i 8 month battery
ANSWER : Was the tractor new when you baught it? if so you never know how long that battery sat before you bought it. not sure where you live but if it has been cold alot where you are there is another reason. Those little tractor batteries don’t have a whole lot of starting amps and if you start it while its cold and don’t let it run for an hour at least it cannot recharge. Try a new battery if not look at the alternator as your next problem. good luck.

Motor will not start. Plug is igniting has spark. seems to be to much gas. [email protected]
ANSWER : Hello,

First thing to check would be your air filters make sure not blocked as this will act as the choke if blocked and will flood the engine,

If all is well remove plug and remove as much excess fuel as possible with compressed air etc, then reassemble and see if it will fire,(With full throttle and NO CHOKE) you may have to repeat this a couple of times…

Once you get the engine to fire it may geep running if the engine was just flooded otherwise if the engine floods again then you will most likely have a problem in your carby mabie a piece of rubbish under the needle valve holding it open causing the engine to flood and the carby will have to be cleaned and tank flushed

Good luck with it hope this helps!!!!

Kind regards
