  1. If you didn't notice oil leaking out around the oil seals, you are probably in good shape. If need be, you can replace them later, after reassembly. (I have a video for that!) One of the valves may have a mark on top (like an X) that would indicate the "Exhaust" valve. Otherwise, I find that the springs are nearly identical and it shouldn't be too big of a deal if they get switched. But in the future it's a good habit to keep them separate and labeled. Thanks for watching.

  2. I have a similar situation with my snow blower, the oil plug came out while I was blowing snow. I have it completely disassembled. I didn't know much about this stuff when I took it apart. I did not take the oil rings out. Do you recommend I do? I also didn't identify the vale springs and lifters as to where they came from. Will this create a problem for me when I put it back together. I'm following this series as I go and it has helped me tremendously. Thank you very much
