Hey Guys, new here to the forums, found you from a google search. Ive got a argo conquest that sat for a while and gummed up the carb. I took the carb apart and cleaned it out, drained the tank, fresh gas, basically did a nice tune up. I got it running OK, but it has a nasty cyclical rpm surge. I took a video, maybe you could pinpoint it by just seeing the duration of the surge. Any help would be much appreciated.
