 MR> What was worse was point ignition systems using transistors. The

I've heard of them icing up too.

Yes, that is a problem.

Sometimes I wonder whether the increased efficiency and peppier
performance is really worth the increased difficulty and cost to
do what would have been a minor repair on an older engine.

    Our task now is not to fix the blame for the past, but to fix the
    course for the future.
