Does this mean you are using the original parts? That may be the problem. Ive never seen a single MC without the check valve. Maybe the kit will have one in it. Like 3B says make sure the ports are open. One is a very small hole. Poke a tag wire through it to open it up.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
