The throttle cable is easy to reinstall but youll need a pusher spring so the throttle snaps back positively........
On the cable trunion on the carb rotator theres a side thats indented to fit the leaded cable end into...make sure you position it right to seat the cable
Feed the cable into the cable bracket adjustment screw
You put the spring over the cable to the cable adjustment adjuster screw on the cable bracket on the carb,,
Make sure the cable has plenty of slack by turning in the adjusters at the throttle
Crack the throttle wide open on the throttle rotator on the carb with the trunion positioned right then lay the cable into the slot on the carbs cable trunion and let the rotator go so the cable seats into the cable trunion indented end
Readjust cable slack at throttle housing or cable bracket adjustment screw at carb
Good Luck
