Car has been sitting for a couple of months and when I started it today it popped back through the carb, car not running the same right now, usually idles at 1000 to 1100 and now it is about 1500-1600, wideband at idle it is real fat and at wot it is real lean, could this be a power valve problem, any help would be greatly appreciated

The power valve would be the first thing that I would go after.

Found a rocker arm off on the exhaust will this make it idle up on a boost carb

Look at the throttle blades & make sure they're not bent

Like slim said, look at the throttle blades. Back out the idle speed screw and make sure the blades become fully closed the re- your idle speed and fuel. The WOT leaness is caused by the power valves shrinking up and not able to open fully under boost. If you have any further questions feel free to PM me or call the shop. Also we do have those power valves in stock and can ship immediately.
