Rough idle

I dont know if this is the right place to post this but here goes. My 1986 F-150 300-6 is starting to have a rough idle i did'nt notice this until today. I checked under the hood but the only thing i could find was a lose sparkplug. Does anyone have any suggestion's where to start looking to solve this problem? Thanks guys

Plus it is carbed

check the fuel and air filters, check to see if the choke is opening completely, see if it's got bad plug wires, or if one has popped off and isn't contacting anymore. Usually, if it's missing or something, do a general tune up, check your a/f ratio, and check all the vacuum hoses to see if they're cracked or broken, or have popped off.

essentially, redo the ignition system, shoot some carb cleaner down the carb, and replace all the filters and see if that helps.
