Lawnboy Gas/Oil Mix Ratio?
I've a 1979 Model 4500 with a D410 engine (near as I can tell). Haven't used it for years. Last time, about '05, I mixt the gas with Moblie 1 Racing 2T Fully Synthetic 2 Cycle Oil of which I still have. Can't recall what gas/oil ratio to use.
What gas/oil ratio should I use?
