Power Brakes - Runs Rough Now
I just finished my power brake install. Stops ok, but my 250 is now running rough. I'm wondering if its a vacuum issue. I put a T fitting on the vacuum port between the carb and the head. The T is connected to the booster and the PCV valve. The little vacuum ports go to the vacuum advance and the AIR pump. It runs rough, especially when accelerating from a stop. Any ideas?
