ok soo jump threw all the hoops to get it all legal. Go to the place Oh we can put that on our dyno those tires are tooo big. So go home put some 31s on go back. Put it on test it well you go high CO readings. Ummm maybe cus your tring to make it go 60 with WOT. So I wire the secondaries closed soo lil du mass cant open them. Any ways I need to bring them down. Already leaned the carb idel circut. Plaied with the timing. Only other thing I can think of because of the gearing and them tring to make it turn a billion rpm thats why its rich. Im going to check the air pump tomarrow. Is there any thing else i could do? theres a brand new cat on it. Im just lost at this point.
