Reading the codes

I've been getting different codes when trying to figure this 700 out.
It had been a 51 code and I guess I got that fixed and miss read it and was then a 61 code but was still getting a check engine light. It is now giving me a 21 code followed by the 61.
So now what do I look for with code 21
I posted before I installed new plugs injectors crank sensor and fuel pump and have gone through the wiring.
Thanks

02 325 Magnum carb rebuild ?

2002 325 Mag. - I rebuilt my carb. with Moose kit 1003-0513 because I wasn’t getting enough gas or no gas to the carb. and everything else checked out. I also removed the screen/filters inside the gas tank and cleaned. Air filter & fuel pump is new.
2 things I noticed during disassembly were my air/fuel mixture screw didn’t have an o-ring or washer like what is in the kit. Also the main jet I removed said 120 and an “R” with a little square box next to it. The new main jet had 145 on it, which I installed. I also installed the new mixture screw with spring, o-ring and washer. I made sure to turn the original air/fuel mixture screw in before removing which was 2-1/2 turns.
When I fired it up it ran great, idled well, rev’d it a little and ran smooth but when I opened it up it makes a steady chatter noise like it isn’t getting enough gas or to much? So my question is – do you think the main jet is the wrong size from the kit ? Or your thoughts that might be causing the problem ?
Greatly appreciate any knowledge on this !

’02 700 carb diaphragm spring

The spring on the diaphragm keeps popping out and lodging sideways when i pull the top cover off. I have checked the diaphragm for holes and could not find any. The atv will not hardly run when this happens. I have repaired it twice. Any ide why this would happen? Everything is clean and in good condition.
