Hi All!
I have a little problem with my TD100 engine!
When the temperature is cold the engine is strating very good.
I am waiting maximum 10 seconds and after the engine is starting.
But.
After the start the baseic rpm is wavering between 700 and 800 rpm. But this wavering is very fine but I see on the rpm meter. After 5-7 minutes the engine has a good basic rpm . ( about 800rpm )
No smoke, nothing other things only this wavering maximum 5-7 minutes.
The Fast Idle valve is working . And I do not know what is the problem!
Any solution?

Thank you
