I got my choke problem fixed up today -- Turns out that the yokel that owned the truck before me decided that a 1/2" of dollar store electrical tape is more than enough to cover up a wire splice. It had fallen off, and was shorting out on the vavle cover. Thanks for the suggestions! In any case, I found out that the previous owner had also done some modifications on the air filter assembly...Namely, using a cutting torch to hack a 1"x3" hole in the underside of the air cleaner. Why? Who knows... Rather than patching it, I think I'm going to junk it and buy one of the 14" chrome setups, but I'm worried about how these perform when it gets down to -30 or -40. The stock cleaner has the hot air intake from the exhaust manifold for a reason, and I'm wondering how the truck will act without it. Any experiences?
