I've got a magnum 40 2 stroke that screams at wide open throttle and the idle is reasonably good too. PRoblem is the transition sucks bad. I don't have the instructions but I'll be looking for them on the net here real soon so I'm not sure what they say.

Any suggestions?

I'm running 10% in it at the moment and I know a little more nitro will help but I don't think that's a real "fix" I'm sure it's a mixture problem on the low end but I'm not sure what the setting for that little screw should be. I'll likely take the carb apart on that side to make sure it's all clear before I go flying with it again.

Like I said - screams like a banshee at WOT though. Can't complain there - take my ugly stick verticle for ever.
