Hei guys, i own a 1979 Mercedes 123 model. Well lets say its a old gentlemen car, but unfortunately, i m a gentelmen,but VERY MUCH YOUNG, DUDE i m in early 20's. Seriously that car is beautiful. mean the comfort of riding, and i pity anyone who comes and bang me, cuz the body is rock solid. From experience. Anyways, my problem is with the petrol and pick up. i wanna improve the car performance. Someone suggested me to use the weber twin carb, but it will ruin my consumption of petrol. I really dont know much about car mod, let alone operate it myself. Know a bit here and there. So any one of us experience with modifying merz performances..? similar engine with 123,>??? do let me know..very urgently .
