1987 318 Tuning with Summit Carb

One thing. I don't think I'd mention to Summit you've had the carburetor splattered all over the work bench. I would simply tell them no matter what you did, you couldn't get it to run right and it must have an internal vacuum leak. You should have a return form that came with it in the box. You really don't even have to call them if you do. Just fill it out and send it back. But if you do call, they will very likely send a call tag so you don't have to pay return shipping.
