it could also be timing because when it "backfires" it shoots what is either unburnt fuel back up or it shoots up exhaust which if i could determine, could tell me if its a timing issue or just a valve problem. im also thinking it could be just timing because when it idles it doesnt do anything but when i go to rev it it starts to pop but it isnt shooting flames through the carburetor so i still have no clue what is causing this.
