Good points, one and all. I'm suspicious of the fuel quality also, although it did look and smell ok when I drained some from the fuel line. I like the injector idea and will try the test when I return. I'm on my way to town, Pueblo, 40 mi. each way in hopes to find a Haynes manual at Barnes & Nobel or a auto parts store. There's a price to be paid for living in a secluded paradise.
Will let you know my findings with the fuel line test.
