First step is to check your valve lash. You have screw tappets so should be an easy fix.

I'd clean the pilot jet first.

I will look into what you guys mentioned. How do I know how to set my idle timing ? Thanks

FCR carburetors notorious for boogerd up and clogged pilot jets by old fuel, causing a lean condition like you described.
