HP 40 RC

Postby chrisjohn » Sat Oct 24, 2009 7:26 am

I have just purchased replacement cylinder HP 40 GC/piston HP 40 GC and new ring to refurbish old HP 40 1978 aprox.
Is there any special way of running in this configuration other than the usual care of not too lean for first few hours.
Any advice welcomed.
