Sanjok wrote: Yesterday I was mowing my MF and after 30 minutes of work the connecting rod jammed on the crankshaft. I added XADO 2 T oil to gasoline in the ratio of 30 grams of oil per 1 liter of gasoline. I think the reason is the oil, since until this year it ran on regular diesel oil. Who can tell me something about this.

Sanjok, Lew in a ratio of 1:40, gasoline 92 and semi-blue oil or mineral water from the leftovers. For 4 liters of gasoline, 100 ml of oil, + 30 ml of Rosneft flushing oil. At first, everything was very coked and the engine went into overdrive and only ran on 80 gasoline. I started adding flushing oil to 80-grade gasoline, and somehow it cleared up and switched to 92-grade. It seems like you don’t have to pour the rinse anymore, but out of habit I pour it, but it won’t run out. Oil for two-stroke engines, which I don’t pour into a chainsaw in a ratio of 1:50, is more expensive. And with it, on 80 liter gasoline, it also went into overdrive, but I don’t want to experiment anymore after cleaning it. It works - and it's great.

please tell me. I have a MF-70 walk-behind tractor but there is no ignition, what can I install or remake?
