Hi,

I've just bought a 1989 (F reg) City, and I could do with some advice
about a couple of things.

According to the manual, 1989 was the crossover year for 4*/unleaded.
The stamp on my head says 99HD80 - can I safely run it on unleaded?
I'm using additives are the moment to be on the safe side.

I spent a frustrating day yesterday trying to tune the engine but the
points are past it so I am thinking about changing to electronic
ignition. A mechanic friend told me to use a dizzy from a Metro, but
would this work OK on a 998 engine?

Thanks!

Chris

You should be running on 4* but you could get away with running on unleaded,
the crossover point was really in 1991. You should be able to get away with
using a Metro dizzy but use the correct one for you're engine i.e 1000cc use
a 1000cc dizzy etc...

If you do intend on using unleaded either change the head for unleaded or
continue using your own until detonation of you original..... Your choice

Am not sure about your second point but I believe that you'd need an
engine no. that reads 99H/D81 or later to be ok on unleaded.
