I heard from someone that it's fairly easy to clean them. and most likely the coils of the metering unit itself are fine, just the needle is stuck. But I never got around to taking the Rochester block apart, even though I have an old upright windshield and a hatch. Spot on. I used to own a Cessna 150 (named “Lulu”) years ago, and I had an A&P at KGVL where I was based tell me this trick. It works very well. Cheap, simple fix.
