Got my 70 FJ40 finally started today and drove around the block without any problems. That was a huge milestone. I need to fine tune the rebuilt carb and here is my first question of many I’m sure. I pull the choke knob and the flapper does not close. I have to move the mechanism by hand for it to close. I lubed the moving parts without success. Seems like linkage is bidding some but I’m not convinced that is the issue. Any suggestions on what to check first?
