Hi folks,
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 together right.
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.
Best wishes,
Chris
