If the engine does n’t require to start , it could be due to an zephyr filter that is either considerably dirty or clogged . you could figure out if that is the case by trying to start the locomotive when the air filter is removed ( if it starts when there ’s no consignment on it , then your trouble is with a choked or dirty pleat ) .
A clean air filter will allow the best possible airflow through your locomotive engine and past your spark plug in order for kindling to occur , thus have cleaner fumes gas and respectable fuel efficiency ( less fuel emaciate ) .

Check for loose wires around the locomotive compartment or between the ascendancy module or throttle cable television service .
Check that frayed or blank insularity of wiring is not causing shorting on alloy bodywork that would n’t commonly be conducive to electricity such as canvass metal , rubber , charge card , and paint surface .
