woodburnyq50 Posted May 19, 2013 Share Posted May 19, 2013 Got all of the aerox back together went to go for a test ride and there's no power, does not want to move with me on it, but if I lift the back wheel it will spin, could this be the carb setup been wrong, or something else? It did have a 70 kit on before the piston and cylinder went, just fitted a standard 50cc one now tho, any ideas would be much appreciated, desperatly need it fixed Link to comment Share on other sites More sharing options...
woodburnyq50 Posted May 19, 2013 Author Share Posted May 19, 2013 Or could this be wrong jet size? With going from a 70 back to a 50? Link to comment Share on other sites More sharing options...

wild foamy Posted May 19, 2013 Share Posted May 19, 2013 If you're running a carb that is set up for a 70cc but with a 50cc engine it will be overfueling, resulting in the lack of power, check the colour of your spark plug, should be a chocolatey brown colour on the end although i suspect yours is running rich so it may look black and sooty Link to comment Share on other sites More sharing options...
woodburnyq50 Posted May 19, 2013 Author Share Posted May 19, 2013 I had it on idle for about 20 minutes took it out and it was a really dark choclaty brown, close to a black, I will pop to the dealers on tuesday and see if they have any jets in stock, fingers crossd they do and I can get it running thanks for the advice lads, will update when I get new jets Link to comment Share on other sites More sharing options...
woodburnyq50 Posted May 20, 2013 Author Share Posted May 20, 2013 would both the main and pilot jet of been changed when it got the 70cc kit on it? so i would have to replace both of these? or just replace the main jet? Link to comment Share on other sites More sharing options...
