Hi all,
Further to my previous post, and Andy's lengthy reply, it is possible to use
the carb and manifold from a Renault 1.7 from either the R19 or 21 with some
modication. You need the 1.7 energy engine though, which has a much better
twin barrel Weber carb.
It will need re-routing of vacuum pipes, and some blanking off for it to
work though, but once fitted and working is warpy-base free.
