the clunking resonates in the wing like a drum and I don't like the sound when flying.
Any suggestions for a clunk that won't rattle?

You can buy a YS foam clunk. It's foam with an alumiumium core and they make it for their pumped F3A engines (30% nitro) to keep the air bubbles out of the line. The softest clunk tubing you can get would be better as it's fairly light (dry) but when fuel soaked tends to follow the fuel around just fine.
Central Hobbies should have them (YSE4720) but they should be available from anyone that selss YS engines, or google "YS-F2083".
