Yea, only went with the aftermarket reed block to try to eek a little more performance out of it. Definitely not something you need to do. I left the spacer in there, not really sure if i should have. Maybe I should rip it out and see what happens, probably doesn't matter. I'd go with the one without the cable choke, I regret getting the cable style one.
I've cleaned and checked point gap and timing on it before. It's the same magneto/stator as a Puch E50, so you can follow all the guides for those. 17mm BTDC.
