Hi Bernard, thanks for the info.
How did you go with valve seat recession,pinging etc on the PI's with
unleaded and where did you source new rubbers for the injection.
Also do you have any circuits to drive the leaded sensor and a display(meter
etc) to display mixture or are there bosch units or others as full mixture
display kits.
Thanks for any help you can give in Advance

Hi Joe,
Yep, there are special leaded fuel versions available from bosche. I
understand they are significantly more expensive than the unleaded type.
The local repco should be able to help.
You are very lucky still having leaded fuel. NZ lost it several years ago
as a result of the local pressure groups (silly thing is we have replaced
the lead with other wonderful poisons such as benzene and tolulene and lots
of it!).
If Aussie does go to unleaded, be careful with your PI. Straight unleaded
fuel is fine as is straight leaded fuel. However, I found that the mixture
of leaded and unleaded (by the petrol stations during the changeover time)
melted all the rubber between the fuel pump and injectors (that's a lot of
o-rings!!)
Cheers
Bernard
