Turns out he's been there for a long time, right? At least six months. If this is the case, the gasoline in the carburetor has evaporated over time and the colloidal substance in the oil has blocked the measuring hole in the carburetor, so it cannot be removed. Also check the amount of gasoline in the fuel tank. Loosen the oil drain screw under the carburetor to see if there is any oil. Remove the high pressure cap from the spark plug to check for sparking (unscrew the high pressure cap). to expose the wire core inside). The metal parts close to the machine are about 5 mm away and pull the motor). If there is a spark, there is no problem with the ignition system. Then unscrew the spark plug and check if it is lit. the candle is good. You can put it on the high voltage cap and lean against the metal parts of the machine and shootCheck the engine to see if the spark plug is in good condition. If there is a fire, there will be. no problem. Focus on checking the oil line and carburetor. I hope this helps you.
The reasons for the slow response of 28 volts from the generator at the start of the truck are as follows:
1. The battery truck has insufficient power. Battery power is not sufficient. You can use a voltmeter to measure the battery voltage and check.
2. Excessive carbon deposition. The spark plug gap is too wide and there are too many carbon deposits.
3. The high voltage cap is defective. It is the high pressure cap connected to the spark plug which is defective. If the starter motor can turn the engine during electric starting, but it cannot catch fire, you need to check if there are problems with the spark plug and high voltage electricity, carburetor, filterair and exhaust pipe, cylinder pressure, valve. distribution, intake pipe, etc.
