I was given a big front throw mower the other day. Old, but in fairly nice shape as it's been garaged, for the most part, for the last 25+ years. I got the engine running yesterday and had intentions of using it on my edger, but the gas tank is too big to make the switch feasible.
So, in light of that, I've decided to give a go at getting it operating again. Before working on the engine I removed the main drive chain. It is all rusty but none of the links are 'stuck'. It will wrap over your finger easily. I'd like to remove the rust in the least environmentally damaging way possible. I've read that soaking it in vinegar will do the trick.
Anyone here tried that?
BTW, the engine fired up with just a check of the plug and oil and a little starting fluid. Seems to run just fine, no smoking either.
