Idle surge with choke open.
Hey all,
Got this 390 fired up and the Idle surges with the choke open. It calms down when you choke it. I have the distributor vacuum advance hooked up and the PCV hooked up to the carb spacer. Theres a big vacuum nipple on the back of the carb which I have plugged. Does this seem like a vacuum leak issue or float level? I re built the carb with a kit.
