Help!, I've searched but come up empty on this one..
My moped ran great until I put a high-flow filter on it, when I noticed it was starting to run a little lean (obviously). So I drilled the jet (stock size 47 according to haynes manual, not labeled on the jet), but got a little excited and drilled wayyy too big. I ordered a new one from treats (size 50). It'll start and run with the choke on (albeit very slowly); and it'll idle with the choke off - however, if I give it any more throttle than that, it'll rev up for maybe a second, then die. Solutions?
