I have an MT2 18SS

I got it working pretty well today...better then usual. I dont know why it didn't want to run the other day, really weird
I leaned it out today and it pulls pretty hard.

It looks like the little nut and the linkage from the carb has come apart...so if i hit the brakes...i have to tap it a few times for it to work.
Would gluing it back together be a good idea?
