Thank you for answering!
I am not sure how was carb cleaned, but I know that I took it to the best guy in town to clean it. Member petak was also there few years back with his carb, and he took 500 km trip to this guy, so I believe that he knows what he is doing. After him carb was ok, little to high idle, so I bring it down just a little bit and then I started to experiment how would car behave on different setting because I had problems with engine shaking on idle. When engine stopped shaking, I left it on that setting and then, after some period I realize car was slow.
Yesterday I set carb on 1,5 turn to the left, low idle and engine was turning off while breaking, it was shaking, not pleasant to drive. Then I took it to the open road, drove about 20 km with full throttle, and in some point when i put it in neutral it turned off but after that, when I get back in town, it was more calm on idle, but still shaking (not turning off even on low idle) while breaking. Today I made a short test drive, it started up with no choke after a night in garage, feels better to drive, but still little problems while breaking.
I believe the car is congested because it sat down for 6 years and the first owner was older woman for which I believe did never took it in higher rpm. Now I put 100 octane fuel in it and I will see how it will behave in further days.
If you think different, please tell me, because I don`t want to damage the engine (although we all know it is unbreakable
) while forcing it.
