In a previous video, I attempted to repair 4 free chainsaws. This Husqvarna 440 had low compression and wouldn't start so I set it aside, assuming it needed a new piston and cylinder. I cannibalized the oil pump from this saw to repair one of the others so I needed to replace that too. I was able to find aftermarket parts for around $50 bucks so I decided it was worth trying to fix. See the links below for the parts and tools I used:
