what is the correct oil?
just 2-stroke oil you can get from costco/sam's?
how much oil does a weedwacker or leafblower use?
I go thruy ALOT of small engine gas and use 10% eth but every year or so I need to take the muffler off and burn the spark arrestor screen of with a torch as it gets "glazed with corn syrup".
Most weed wackers take 40 to 1 (3.2 oz of 2 stroke oil to 1 gal gas)
Most blowers use the same.
If not 40-1, it's 50-1 (2.56 oz of 2 stroke oil to 1 gal gas)
It's not really rocket science just a matter of making sure the piston/cylendar gets some lube (do you really measure to the 6/100 of an oz ?)
I've been putting 40-1 in my 50-1 engines (chainsaw and hedge trimmer) and then adding a touch more of gas for 5+ years on the same tools.
