Hi:
What would cause a modded G26 to scream on first start up? I choke it like my other ones with the finger over the carb and pull until finger is damp and fire her up. Works well. With this one it just screams and I have to idle it down with the Tx. I am just learning about 2 strokes but this cannot be good for a cold motor. Once it has been started it seems to be fine if I have to re-start it. It also does idle pretty nice. 257 carb with 2 L and about 1 on H.
Any ideas or suggestions

Regards

Sounds like the low end needle is lean try backing it out to 2 1/2 turns.I would also go 1 1/4 on the high needle.
