I went to this guy's house to buy a Dellorto carb from him for $60. Me and my fiance ended up staying for dinner and talking about mopeds most of the time. He is a year-round mopeder like us, and used to fix mopeds in downtown Toronto. We saw his photo album with chrome and gold plated mopeds and stuff.
Anyway, this guy is pretty clever with mopeds, for example he put a Batavus head on his Puch to increase compression and make it go faster. He told me how to modify a carburetor jet using these really small files made for cleaning the tip of a mig welder. To make it smaller, he fills the jet with solder and starts over again. This interested me because my Torrot had a #64 jet in its original Dellorto carb, and the biggest jet I have now is a 52. It only runs with the choke. I have a deadline to get this bike up and running and sold, already have a buyer, and not much time to wait for a new jet to be shipped, so I might just try this method out.
We told him about Moped Army but he doesn't touch computers, it's too bad because I think he would have a lot to add to this group.
