I managed to get this old (1971, I think) Stihl 050 fired up over the weekend. I spent a good while cleaning the deep layer of varnish out of the tank and rebuilding the carb and fuel line.
There's still one problem. On this saw, the cylinder lays down flat with the spark plug pointed right back at the rear handle. I have about 4 or 5 different plug wrenches and I can't fit any of them in there to tighten the spark plug. So, while she runs well, after 25 seconds or so, the plug is vibrating loose.
I'm thinking I could get a spare 3/4 inch socket and grind some flat surfaces on the socket then use an adjustable wrench to tighten the plug, but maybe someone knows a trick to tighten these plugs?
