Hi

I'm trying to find ignition timing settings for a marinised BMC 803
engine (as fitted to the early minis/minors and Austin A35s). The
engine has been recently overhauled and I believe it has been fitted
with an unleaded cylinder head so would it be necesssary to retard the
ignition to run on u/l fuel?

I also need contact breaker and plug gap settings. Could anybody
please assist?

Many thanks in advance

MJ
