Choke's been adjusted multiple times by my mechanic because it had a hard time starting. Even he was racking his brain as to why it was so finnicky, one morning the engine kept turning over and wouldn't fire, I took off the air cleaner and the choke was stuck shut not letting any air in, I cracked it open and it started immediately. He also changed the springs for the metering rods and I don't think it's affected much.
