Up in flagstaf Arizona allmost all People that have trail blazers Were complaning about the same problem on there quads.The problem is the quad would
intermitantly not rev. It would only run at full throdle but bearly. Until you turn of the gas and hold it at full throdle until it revs.Then you turn the fuel back on and it
will run great. The geting is right even the pilot get. All the jeting is done by a exaust temp gage. Any info?
