Hi guys, i am having an issue with a 2 cyl motor, that i think is fuel related, maybe too rich and valve lash not adjusted since it has 99.000 km. Spark plugs are deep black and no sign of oil, so just carbon.
It can't keep idling after 2-3 minutes after cold start, and if running constant speed/rpm (low speed) it sputters. Initially i thought it is an coil problem, but it starts to make sens a bit more as mixture problem. Previous spark plugs were nicely coloured redish as should be. I have attached some secondary waveforms that don't look right to me.
I've attached so many pictures since me personally i can't figure out a problem certainty fuel vs spark
i've added as many captures from data logging i could
