Replacing piston rings is difficult if you don't use them often, you should be fine.
You cannot yet set the ignition time.
As for the question you raised, the power required to start the engine is much higher than the rated power. For example, the power of your 1100 watt electric hammer is about 4 times that by the time it starts, that's about 4400 watts. When the motor is running, the power is doubled to 2,200 watts. Your big motor with a maximum power of 2.7 kilowatts certainly won't be able to handle it.
Also, there is a question mark as to whether your generator's rated attack power is 2.5 kilowatts. I estimate yours is only 2 kilowatts, with a maximum of 2.2 kilowatts. Another 20% reduction, less than 2 kilowatts.
If it is not used for a long time, you should clean the carburator, mainly by cleaning the oil hole.
Newer machines can usually drive it, but it's definitely still difficult. Once started, it will return to normal.
But the load is too heavy, and many parts such as piston rings will wear out, the compression ratio will decrease, and it cannot operate normally.
Possible reasons for automatic generator shutdown:
1. The starter turns weakly
1 When the starter switch has poor contact, it trips. running the starter without power, resulting in abnormal shutdown
2. When the clutch slips, the diesel generator will also start abnormally.
3. When the bearing liner is worn, the diesel generator will not start normally and stall abnormally.
2. Difficulty returning gears
When the contact part of the switch melts, the generator diessalt will not work normally and cause abnormal automatic shutdown.
3. The starter does not turn
1. When the battery power is insufficient, the starter will not start, causing the generator set to stall abnormally.
2. When the connection line is in poor contact, the starter will not be able to make correct judgments, resulting in failure to start.
3. When the starter itself has a circuit fault, the generator set will also stall abnormally.
