Hi guys sorry I haven't got back to you on this. In Utah you have to spend at least $100 to get it to pass after failing the first test. I did...plugs, wires, etc. Off to Murray....he said to rebuild the carb and come back to have it tested. I did and it didnt. Hydrocarbons just over....So they gave me a 1 yr waiver. In a couple months Ill have to do it all over again.
