EC300 Idle Revisited.

[Ud_luz]

OK guys, I'm ready to throw this POS carb in the trash. I've got the same issue he does: http://www.gasgasrider.org/forum/sho...highlight=idle

There is utterly no way I can get a consistent idle. If you even touch the idle air screw the bike will idle extremely high or almost not at all. This is not a needle, MJ, PJ, air leak or float issue. There is something fundamentally wrong with this carb. Surely somebody has figured out what to modify or what carb from another bike will properly work. The similar carb works perfectly on KTMs, why would it not on this bike? I don't buy for a second it's squish or head design, there is some kind of fueling issue that causing the carb to radically change AF with a very slight adjustment.

Is there a definitive answer for this carb or what's a good replacement? I thought I was very good with carb tuning and I have it working perfectly except for this one issue.

Thanks.
