Engine is running like CRAP

[Russell]

I know it needs a good tuneup for sure. Its not just me starting it to take a listen every once and a while, since 1999 the truck has just been started, moved across the yard and shut down, it hasn't done any long distance trips at all, not even the chance to warm up. I guess it just needs a couple longer trips and some fuel additive to clean things up a bit. I plan on changing out the air filter on the carb as well as the plugs and possibly the distributer cap. None of them have been changed in probally ten years.
