BR the valves sticking on the cold start is classic varnished up guides. When the engine is hot everything moves but when it cools down the guides get very tight. Fresh fuel on top of the tar sludge was probably sending "thickened" fuel to the engine. The 401 in our 47 Clipper sat for 24 years in a barn. Had tarred up lines but tanks were pretty much just rust. Eventually had the tanks blasted inside and out and coated inside and out. Google up gas tank repair or recoating and you will see outfits offering the service. Ours have been good since doing them in 2004. Sounds like we have the same baffled 42 gal tanks. We did Myrtle Beach, SC last week of June. Did the 625 mile return to Philadelphia in 1 day. Glad you made your OH trip.
