JG AUG Full / Semi Auto Trigger Problems

[LeoGaunt]

Hi Guys, wondering if anybody could help me,

My JG AUG's trigger is only shooting full auto and not semi, normally a short pull is semi and to pull again clicks and it fires full. Since I took the gearbox apart I've been having problems with this.

 

I think perhaps the trigger assembly under the tappet plate on the gearbox is the problem, maybe the V shaped contacts need pulling apart so it takes longer to contact or something i'm not sure.

 

Any help from someone who knows how this works will be greatly appreciated!

 

Thanks, Leo
