Just seeing if anyone has tried to use one of the adjustable off-brand CDI's before. My SX has a 300 engine, and I had to borrow the CDI from it, so I'm looking for another now. The one I've found is made by 1PZ, #LT3-B01. After some digging, it is used on Carter Brothers GTR250 & 300 go carts. Looks identical to my CDI with the exception of the adjustable timing curve. Just seeing if anyone has some info to share on it.
