Thanks for your feedback.
I'm starting a rough journey into the depth of the injection system.
Many hours of reading is waiting for me.
Hi there Africa_twin,
The TA700 engine is something different from the AT engine.
One of my friend ones said that the TA goes vvvvvvrrrrrrrrrr and the AT goes gggggggrrrrrrrrrr...
Everything A-Wind mentioned is correct. the carb feeding is old. better fuel/air mixture, all the time, means better fuel consumption, better throttle response.
Besides, one of my carbs shows wear signs in the float hinge.
