Are we looking at just another "gimmick" here?

Yeah, mostly old round engines. But I think the Bendix "dual mag" is still produced and used on Lycoming engines.

Round engines? Do you mean radial, LOL

Yep! Worked on a lot back in the day. From the Shakey-Jac R755 up to the Wright 3350. The Pratt & Whitney R2800 will always be my favorite. They don't make them like that any more. And it's a damn good thing!

I know I am late to the game here.
The dual plug head is used to get a complete burn of the fuel or better than the one. However I have only seen this work well with 4 strokes. A more efficient engine will net better power and also better fuel economy. I can't see the CG seeing any sort of benefit especially with one CDI running both, even if the guts of the CDI are bigger.
But who knows. For that money I will toy with a second engine.

Same here,,, I don't see an advantage to this less a clearer burn """maybe""". A opertunity to keep running if 1 spark plug fowls...

Disadvantages as stated above in other posts...

A game changer would be a 125cc engine,,, not sure how a person would get it started if it had good compression,,, Ha...

A steep down hill run,,, jump down on the seat and dump the clutch....

Oh,,, Oh,,, Oh,,, dam,,, just skidded off the bottom of the tire... lol

It really helps with all this cold weather. See Dad's just a little mad, he still cares though. Thinking about me and keeping me warm and healthy even when he's upset. View attachment 161548. ......
An underwear cat keeps my underwear warm while I poop.

Oh my God. An underwear cat! I need one!

She's a good girl. If I don't let her hang in the underwear hammock, she wants to sit on my lap. Lol.

An off set key(s)on the mag and playing around with it will do wonders... Filling the head with plugs should add some compression but as is junk... Maybe use a long wire on one pointed at the exhaust port and short at the intake to separate the sparks... Or a different heat range...
