I have alot of 2 stokes and repair neighbors stuff all the time. I dont get much if any gummed up ones. I think the oil in the gas helps immensely in preserving it. Usually its the fuel lines that get hard and break or the diaphram gets hard. Sometimes the carbs get clogged but there is evidence of dirt not the usual gunk you get in 4 stroke bowls. Plus they have plastic tanks that dont breath as much so you dont get as much condensation. I run 87 mixed around 20 :1 in all my stuff but nothing sits for very long. When it does I find the gas evaporates off and i end up with half oil and a smoke show. I know some people put some atf in their 4 strokes to help out and Im sure it doesnt hurt. Iv never been a fan of stabil or other preservatives. It seems engines that have had it always run like **** and you need to clean out the fuel system anyway. Atleast when they have sat a few years. I sharpen my chains with a dremel while on the saw it goes quick. Usually every tank. I have a tecomec easy grinder i never use if anyone wants to buy it.
