All started with a dirty carburetor. It was only running with the choke on so I decided to clean it. I found a debris in the little passage on the side of the bowl. I cleaned all the other orifice with compress air. Now it run extremmely rich, it smoke a lot. The only way I can keep it running is to close completely the low speed needle. There is a fix high speed jet so there is nothing to adjust on the high speed side. I run not too bad at idle but when I try to gun it, it hesitate and smoke a lot and eventualy will stall on rich mixture. I am guessing I blew a little piece whit the compress air but I have no idea what.
