fuel

[Jared Mk3]

You can use LRP (if you can find it nowadays), otherwise unleaded with an additive, if your head hasn't been converted to accept unleaded fuel. Might be worth doing the conversion.

hi there

can you tell me more about the conversion ?  what needs to be done ?

Basically hardened valve seats are inserted into the head. Most decent engineering shops should be able to do it. I'm busy getting my 1000S head converted to unleaded.
