Hi all, Assembling my new qq 102 w/evolution 116 & wanted to hear the engine & break it in. Bad part was the evolution exhaust i got for it would not even come close to fitting in the cannister box. I might be able to get a 60-65mm can in there, the evos were huge, maybe 80-90mm. So i just ran the engiine for a few minutes with no pipes at all. well it wont idle for crap, it seems like its running too rich, cause breaks into a 4 stroke. try leaning, no help, try richening no help. did get it somewhat better by adding fuel over the factory setting. Am I doing wrong running open exhaust & is that causing the crappy idle?
