Primary chain adjustment procedure

[andre g]

copper heating until cherry red and quenshing softens it, thats a fact.
Primary chain adjustment I fix the screw until I can hear noise is changing and the idle speed dont decrease.Then I lower the screw a bit and fix it.

For our purposes (getting a nice, soft but resiliant, seal) it makes no difference whatsoever if copper is left to cool in air or quenched. The advantage of water quenching is that it loosens the oxides and scale, leaving a cleaner part. Quenching from dull cherry red most definitely does not harden copper.

Bugger me, I just skipped 6 years of my life. Rip Van Winckle and I are heading to the pub to catch up.

Doesn’t matter, either way will wrk, and if you you tighten down said washer whilst still warm even better.

Okay, we didn’t get into the pub … the pub is closed and everyone is wearing masks, the Ebola virus must be serious. Rip reckons the mask wearing is because of AIDS.

Bugger, now Rip wants me to drive him to Sydney so he can pick up the new 81 Jota he ordered from Eades before he had his nap. This is going to end badly.
