A simple solution that has worked well for me is to spray a little WD-40 on the releases when ever they seem to be somewhat sticky. It has worked great and I only need to spray them maybe twice a season. Also helps keep the corrosion down on the compression release exteriors.

+1. I had the same issue on my front cylinder after warm up. A bit of WD-40 and manually cycling took care of the need to crack the throttle to close the valve.

Zach - thanks for the hint on this one. I noticed the other day that it sounds like I have some air leaking when I accelerate hard. The engine really sounds like she's hitting hard. Any hints on checking for an intake leak? I have the Heavy Breather. Do I just inspect the gaskets and such?

With the engine idling, spray some carb cleaner around the intake seals. If the idle speed increases as the carb cleaner is hitting the seal(s), you have a leak. You need to make sure to shield the AC element from getting sprayed to get the optimum results. If you have a leak, first thing I would do is look for a loose bolt, but don't over-tighten them. If that doesn't do it, replace both intake seals.

Even if they stayed open it would not hurt the motor other than make a mess.I would still take your out and loosen them up if you can.
