[Healeys] pointless points

[Derek Job]

I have to agree with this. After years of resistance for originality
reasons I finally switched. In competition I was experiencing an engine
fluffing at high speeds, almost like hitting a rev limiter. My points were
gapped weekly and they were changed several times a year but I couldn't
solve the problem.

I went for the Powerspark magnetic system. Very simple to fit, no external
parts and very reasonably priced. Only B#29.00 in the UK. It is exactly the
same equipment as the Ignitor and also the Alden version, which is sold in
the UK for about B#80. There has been a huge difference in top end
performance with the fluffing completely eliminated. Another surprise was
how much smoother it is at low revs as well. The system compensates for any
problems caused by wore distributor shafts and provides consistent timing
across the whole rev range.
