Max,
I get a lot of mowers that have had ethanol in them and there is no way you can then get the main jet out of a Chonda carby but I can always get them out of a genuine Honda carby, obviously there is a difference in the alloy the body is made out of. I sell my 2 strokes for between $80 and $100 and have no problems getting that for them, only problem lately is I haven't had time to build any because I have been working on other stuff. Hopefully this winter I will just concentrate on building a pile of 2 strokes to sell next mowing season, I have missed this one.
