Personally, I’d want to know what caused the damage. Not likely it sucked in a bumble bee and did that – more likely a bad reed, reed fastener, rod cap or some other part that is broken or worked loose. The rods and crank you’ll be able to evaluate when you get it apart – if it’s the reed or something like a carb butterfly screw, that’s easy to fix.
