Hi all

Thanks for all the opinions Could be low end, although I spent 3 weekends fiddling with it, and then every guy at the field with a screw driver had a try untill I was so confused about where the needle should that I turned the needle in completely, blew into the carb with a piece of fuel tubing attached to the nipple and slowly opened the low end utill I could feel air going through and opened it another half a turn ... I will tinker a bit more this weekend. It does spew out quite a bit of smoke when it trasitions from idle to WOT but does not splutter or die, so I guess I could lean it out a bit more.

Good point on the age of the engine, I have no idea how old that engine is so, it could be 10 years old but only have been run 10 times.
