I use starting fluid on my chain saw after it has sat a long time between uses. Any starting fluid I have bought over the last few years has lube in it and it appears to be a fair amount. It leaves an oil residue behind when sprayed. Properly used though, any starting fluid should be OK (lube or no lube) as no liquid should ever reach the cylinder! The natural lube residue in the cylinder should never be washed away. Most people use way too much starting fluid .... only enough is necessary to reduce the flash point of the gasses in the cylinder to make starting easier. An overly rich or lean mixture of gas / air in the cylinder will ignite easier when starting fluid is used. Too much and you get the all too familiar arm jerking kickback that most people experience.
