Starting compression bleeder: allows easier starting as it kicks the valve open slightly at starting RPM , then swings out of lifter range when running by centrifugal force. Only thing plastic cams are good for are using them as cores for lobe angle changes: cut the 2 lobes apart on the shaft, move them slightly for more or less overlap then drill and pin them to the metal shaft. Once you find the right lobe separation (longer or shorter overlap) find a custom cam that matches it in METAL!

Cheers Dick. Good tips. Don't like plastic cam shafts though.

There is a very good reason why car and motorcycle engines have camshafts made out of chromium steel, nickel chromium molybdenum steel, or cast iron.
Absolutely ! Cheers mate 👍🏻🔧
They don't make thing's like they used to Dick. Happy New year to you and your family when it come's. 👍
Indeed they don't. The motor I just gt running from the scrapyard is more than 70 years old and will run for decades yet.
