just bought a new weber carb kit

it sounds like a problem i had but it was not the carb. It was doing that because the exhaust was clogged up because we bored out the first cat and the pieces of it clogged up the second cat and it was backing up the system. so what i did was took the second cat off and left it like that (better sound better performance), but where i live in arkansas and they don't inspect vehicles.

mazda mx-3 will work also
