I have an '85 350 Blazer. Its a great work vehicle, to and from work. But the reason I bought it was to go off-roading. The only problem is that when I have fun in 4x4, it starts to crap out on me. It doesn't get hot, it sounds like it floods or something and then it won't start for a while. When it does start, it will turn off when I try to give it some gas, but will also idle kinda funny. It gets VERY tempermental. So when I let it "rest" over night, it's fine the next day! By the way, I have a q-jet in there right now with an electric choke. 1. You think my carb is getting clogged with gunk because of the high RPMs in 4x4?
