I have been overhauling a Wipac Series "A" magneto. It has been
frustrating. First the coil was dead. Then the impulse coupling was
slipping. So I collected together several magnetos, took them all apart,
carefully noting how they fitted together, and selected the best parts.
Then I found that although these magnetos look standard, there are small
variations. Different rotors. Different shaft lengths. Different numbers
of flats on the shaft. Different impulse coupling designs (and I don't
just mean the drive connection). Different flange screws. So far I've
tried to assemble three combinations of parts, and none quite fit
There are a couple more combinations of parts I haven't tried, so I may
still find a solution. But I've been increasingly tempted to fit a Lucas
SR1 magneto instead. I'm weary of assembling different combinations of
parts, and I want a reliable magneto.
It's been a while since I looked at an SR1, and I can see strengths and
weaknesses in the Series "A" design. How does the Lucas SR1 compare to
the Wipac Series "A"? Which do people think is best magneto, in terms of
reliability, durability, intensity of spark, etc.?
I know this is likely to be a controversial topic. I've heard plenty of
conflicting opinions. So far I haven't found a consensus.
