MagnaSpark

Try it with the shipped in place springs first to see what it does.

You’ll probably like it as-is.  I have a MS II and love it.  I’ll check to see what color springs I’m running.  They’re super-easy to change, right under the rotor.

BTW, while it’s really nice to have a dizzy that is easy to change the advance curve (or lock it out for use with a crank-fire setup), the REAL benefit is a much better and closer tolerance mechanical assembly that is much more stable and doesn’t allow “spark bounce” all over the place.  The original, German Bosch 009 disti was very good, but the hordes of non-German knock-offs are all pretty poor unless you get a well built one, like the Magna Spark (either one).

I have a new old stock, never used, still in the box German Bosch 009 I’m willing to sell, if anyone is interested.

Somebody's always interested in OG goodies, El Gordorific. How much?

Stan, I have an original light blue cast-iron "019" if you want it. It most probably needs a rebuild, it was rust-frozen, but I freed it up with some PB Blaster.

I changed my MS springs to the lightest I believe blue. It solved my acceleration stumble/flat spot.

I suppose when I do the switcheroo, I'll have an 009 available.  Can't say about its heritage, likely not born in Germany.  Mr. Piperato gave it poor marks when he was doing a  "proper" tune of The Baron a few years ago, as I recall.
