Sorry for the background noise, I think my neighbor was building a moped too using hammers.

I found with my two Za50 rebuilds, both of which I used two Treats cranks, that I had to file the woodruff keys down to slide over the stock flywheel. It seems the groove on the new cranks are not as deep. A nice metal file and a couple of trial and fits did the trick. Also threaded and put a hex insert down the decomp hole just as extra insurance against blow by. Red locktited that sucker too, good call. We don’t need that hole! Jealous of the fancy torque wrench! What carb Travis? I’m using a rebuilt original 15 Bing, forget the jet in my 65cc Airsal kit and it’s the sweet spot. If you want to know, I can take it out and check it. Little out of it because been doing a kitchen remodel for the last six months. Almost done and ready to get back into it. Wife said no mopeds till done with kitchen. Update, after watching Travis’ videos again, I think I did sand the sides of the woodruff instead of the top, so ya I think it was the sides I filed, but after, no problem.

Oh interesting! I feel some solidarity there with the woodruff key !
I'm going to rock the 15 bing on this like the moped gods intended - I feel you on the kitchen remodel too, house stuff is never ending, mopeds can be the reprieve :D

Looks good! Can't wait to hear it.

[@TravisTutorial]

Thanks! And you and me both!

[@markyounggren3649]

surprised you didn't go with the Gila, but old-school polini is more nostalgic and better in my mind for a sleeper look

[@TravisTutorial]

I dig that! The gila is a bucket list kit too. There is a local machine shop here willing to do the work to add material to the case, so someday I'll have a Puch with one
