The last post you saw some pictures of a freshened up E13 and 5 speed.
At the weekend we had some nice weather so a few hours where set aside to remove the E10 with 4 speed and fit the E13 and 5 speed.
I gave the Carb a ultrasonic bath treatment and a rebuild with nissan rebuild kit. The carb did have some old nasty looking fuel remains in the bottom of the float chamber.
