Perfect upgrade
I just needed to replace my old factory cam that had spun the gear. What a perfect surprize. This cam automatically decompresses until the engine starts. It works perfectly. Not to mention nice low range and mid range.
I ripped off my decompression lever and cable and never think about it, just kick start it and go.

Thank you Hot Cams!
