I've got a cheap little chinese 1000w 2 stroke generator, and it works to beat heck. For what it cost me I keep waiting for it to blow up, and it just keeps humming along.
It runs an electric impact wrench with no problem, so I'm certain it'll run your saw. If you want, I can fire it up and try it, we've got a pole saw with an electric chainsaw on the end we could use. (for another 40 bucks I could have bought the step up polesaw you could take the chainsaw off of, and boy am I kicking myself for that)
Anyway, I bought mine off ebay from a place in Van. about 5 years ago for 100 bucks shipped. There's a place in Cal. that sells what I"m certain is the same thing in a different color with a different name on it for 139.00. I'm actually thinking of buying one as a spare since we bought a little deepfreeze to take up N with us this year. (2 trips cut short due to hanging meat and warm weather is enough!)
If you want the name of the store, just pm me.
