Re: Jonsered 2040T over fuelling?

I tried a complete kit over the weekend (gaskets, needle and screen) and it is still flooding. Very frustrating.

I followed setup procedure for walbro wt carb and have the needles at 1.25 turns out. It floods so fast from opening the fuel line that I think needle adjustment seems unlikely. Will try though.

The carb to cylinder gasket is not looking great but I guess it must seal as the pulse is still good - I am getting too much fuel rather than not enough.

Also, when it does run it seems to leak a little fluid from the crank seal, chain side not generator side. It's not chain oil as I have blocked the port. If I am loosing crank case pressure, will this effect anything?
