i think i am running rich

[ugp134]

ok in auto we have this project car. its a beast, but i think we are running rich. you can smell it but the teach. says that it could just be carbon deposets. we checked the plugs but the description for plugs that are run rich and with carbon deposets are the same plug. but also the idle is running really rough. i already kno the trick to choke the carb then mist some water in to it to get the plug to burn hotter. but you cant stop at every light to do that. so i believe we are going to change the plugs and air filter.
