I have a 7yr old Lectron EC2000i ( Chinese made ) portable generator in as new condition ( support discontinued by Aus distributor soon after purchase because of lack of after-sales support). This model was quite popular about this time. It was bought for emergency power supply use only, so it has only had a 5 minute test run each year, after draining and adding new petrol, with no problems till now.
Yesterday, I ran it for longer and after bout 10 mins running it started to belch cloud of white smoke for 5 secs then smoke slowly cleared, and same again after bout 30 secs.
Had to stop as neighbours may have complained. I also added small electrical load during test and rpm adjusted as expected.
Any ideas as to problem or is it beyond repair ??
