Rocket valve cups
« on: 26.07. 2010 22:13 »
Hi Folks  - while I've got the head off, thought I'd check everything out while I wait for bushes arriving.
One thing I'm not 100% sure about is which way up do the bottom valve springs cups go.
I have them with the wider boss to the bottom, is this correct
All the best - Bill
1961 Flash - stock, reliable, steady, fantastic for shopping
1959 Rocket Gold Flash - blinged and tarted up  would have seizure if taken to  Tesco

G'day Bill,
                I'm pretty sure the narrow side goes down. Less area for heat transfer. See which side the springs fit better.
Cheers

The bottom cup centers the springs. Fit it to do this.
