ok, so I just bought a brand new c-70.. well, its just about brand new.. it might as well be.. its a 1981 honda c-70 deluxe.. I can get it to start.. but it dies as soon as I give it gas.. but it idles really high.. and my idle does nothing.. no matter which direction I move it.. but anyway.. I took my plug off of my other c-70, and put it on the one I just bought.. and it started.. once it died.. I couldn't get it to restart.. checked the plug again.. black as can be.. so I cleaned it.. same thing.. started.. then died again.. so I checked the plug.. the thing just done broke on me.. (the plug.) what do you suppose could be the source of my problems? any help would be great.. and I know its not a "moped.." but if thats going to stop you from helping me.. just know that I have a vespa grande too.. and I am a mopedder at heart.. thanks..
