Damm! Thank you very much but it's too late! I've just sold the whipper snipper for parts on ebay! Last time I played with a Ruixing carby I just wasted time and money and I decided to get rid of it before being tempted to spend more $$ trying to fix it..
My success rate in fixing old mowers is around 100% but for some reason, when it comes to whipper snippers, Iļæ½m quite hopeless..
