    Angry Fresh carbs New issue

    First it's a 97 XP with 787 So I did a full rebuild on my carbs gaskets, needle and seat, diaghpram etc...... Well I finally got it in the water today and it idles fine but will bog at ANY throttle. Now it has a pump primer on that gives the carbs a squirt of gas if I pump it and hold throttle open it will run fine at WOT... I'm thinking low speed adjustments are off??? I did the 1 and 1/4 turns out when I installed them.

    Well I think that's where I messed up in the rebuild kit I had like 3 different springs so I changed them......DUMB! So I changed spring pop off was about 35psi issue was better but not fixed. So today I changed them to 25psi springs and will be trying that tomorrow. I also have tried adjust the low speed screws and it really doesn't seem to make a difference.
