[auriga]

I just pull the carb out, clean out and replace all the gasket. Removed A/F screw, and set at 2 turns out. Air blowed all passages, and clean things out. Bike was having problem to start, now it start perfertely. However, I replace the long needle on the top side of the carb. I'm not sure why, now the bike acts like it needs more gas when Im doing hard accelerating. It's accelerating ok when slowly, but losing power when going hard.
What could be wrong??
I visual check the diaphram, looks good.
