I'm back on the road again.! With the new-made spacer in my hands, this morning I've put the carb again into the car, connected all the hoses, tubes, etc.. and cranked the car. All looked fine to me so I decided to go for a ride with her. Have done some 15-20 miles, back home again and the system looks to work properly, no leaks nor strange noises so at the moment, I think I am done with this project.! Anyway, I'll keep an eye to it.
As I restored the heater box with new seals, paint... I replaced the red ugly hoses I had and put the correct ones. Also AM radio has been repaired by my neighbor and now is working.! Voltage regulator replaced for the correct one as well. Next will be to remove the fan and it's spacer to paint them correctly.
