Re: Yanmar 2gm20f
Suprising, the throttle sterted working by itself and now the engine is working great. I guess, this engine was neglected and the old fule staying inside made a lot of damage. The fule injector cleaner did the job, with a lot of playing with the throttle and the shot off valve. But now noticing another issue, the oil level is increasing. After oil and filter change, I left the oil level on half btw min and max and 10 working hours later, on higer throttle went to overspeed and had to chock the intake again. Checked the oil level, and now the level was little over maximum line on the stick and the oil was black. Repalced the oil and filter again but now I will monitor the oil level after every couple of hours of runing time. Any idea what could be the reason?
