Hi!

There is no load, just idling. I have drove it with load, and it only quit a little bit faster with load. The generator is rated at 1.75kw. Load doesnt seem to be problem, whether its big or small.

So short circuit isnt likely here, because electricity is generated.

Bearing on the other hand is possible . Though I would suspect it would lower the power output. Now I tried 1.5kw load with no problem.

To me it feels like its getting too much fuel in ratio to air. Engine doesnt burnout all that fuel, and thats why it smokes. A/F ratio gets worse when engine gets hot. What is the mechanism engine to adjust this ratio? Or is the spill timing only thing that you can adjust?

 Injection timing seems to be correct. I tested it with injector spraying open air. Not sure if this is the way its supposed to be done.

I also cleaned those cylinder fins with break cleaner and brush. There was basically just some black oil /soot that game off  suprisingly easy. I havent measured temperature after cleaning, but I think it wont make a big difference.

Also removed the inlet/exhaust manifold to see that its pettynyt clean.

The smoke is white/Light Grey at the beginning, and gets darker after a while. Not Black anyway

Hi guys,

And sorry for radio silence.

A lot of good ideas here, thank you!

I took a little videoclip friday, and got it uploaded today. Here is the link: https://m.youtube.com/watch?v=Vi6qInlm5FA this is after about 17mins of idling. Cylinder surface temperature was 112 celsius at this time.

Hi guys!

Thanks for your responses. 

Hi JP,

Some questions:

Is it easy to turn over when it's hot? Easier than when it's cold? Or the other way around - really stiff to turn when hot?
Does it smoke at any time when running (and if so, what colour)? Is it smoking when it's stalling out?
Does it gradually slow down and stop, or does it just quit all of a sudden?
If you try to start it when hot, what does it sound like? Wheezy or normal? Do you get any white smoke?

I'm sure others will chime in with questions & suggestions that I haven't thought of.

It doesn't seem to affect engine turning noticeably whether engine is cold or hot.

There is some white/light grey smoke, which seems to be increasing somewhat at the end.

Stalling is not very sudden. It fades away within few seconds. No misfiring, rough idle or coughing. Engine just quiet down, maybe within 5 to 10 seconds. Until that it seems to run normal to me.

Is it possible to attach a video clip here?


Thanks again!
