RE: converted Stihl engine - how the heck do I start it!??
Yeah, WD-40 is better than ether for two strokes. Apparently they changed the formulation a couple of times. We used to use it occasionally like a starting fluid, and then they came out with a formula that wouldn't burn. Now, from several reports I've heard, it burns again and will work as a starting fluid.
I still don't recommend using any "starting fluid" except under the most pressing circumstances....
