Hi everybody.
I've been heavily messing around with these 2 stroke motors, and I just joined this forum. I've been on one of the other forums for a little while, and thought you folks over here would appreciate some of my tinkerings.
Anyway, this is actually not the first prototype, but it's the first "production" model.
As you would first suspect; twin spark plugs need twin ignition.
It's true, but this is not very difficult to overcome.
I've included some photos of the components I used to deal with this challenge.
I decided to use a DC fired CDI from a 50 cc GY6 scooter(I believe) They seemed like a pretty common unit, which I found readily on ebay.
It being a DC fired unit, I had to bring a battery along, which is the part of this system I like the least, especially my awful electrical tape mounting system!
I didn't see much way around the problem that the original magneto wouldn't have enough energy to supply two spark plugs with a hot spark.
With the battery, there is plenty of energy to go around, and a single CDI unit seems to reliably power both coils to deliver a blue spark, much more powerful than the stock ignition system can deliver.
If you look at the head, you will see the compression release. So, yes, there is a third hole, just like the spark plug holes. It is definitely a deluxe set up. I think I will make them in two versions; some with three holes and some with only two.
When they become available, which should be in a few days, I will start a thread in the vendor area here at this forum. There, you will be able to check out cost and availability and such.
So, thanks for having me aboard. I will try to adhere to forum policy to the best of my ability.
Thank you!
