[Jdstep]

Hi all
I recently got a 2001 GG EC 300
It's idles for about 3 seconds then the idle drops and the bike dies. This happens at all engine temps.
I have got a JD jetting kit, currently running red needle on middle clip. 178 main and 38 pilot. Air screw is at 2 turns out. Idle screw seems to make no difference until it's wound almost all the way in.
I set the float level as per other threads and found that it still leaks upright unless it's set super low. To the point where the needle closes when the floats at 35 ish degrees from the carb body.
The bike is also using A LOT of fuel even when not riding at high rpm.
I also find the bike is very spluttery when at a constant throttle at any RPM

Carb has been thoroughly cleaned and reeds are all okay.

The top end is brand new and air filter is clean. There is also no air leaks in the system.

I removed the plug and will attach a pic for anyone that's good at reading plugs

Any help or advice would be greatly appreciated
Thanks
J
