Servus dear oldtimer friends, I very much hope that someone can help me. I have been allowed to call a beautiful BMW 2000 carburetor Bj. 70 automatic my own for 1 1/2 years. So far I had a lot of joy in my BMW but now that it’s slowly going back to spring I want to make it ready for my weekly weekend tours. However, problems have occurred since last summer. After every longer service life you (my 2000) of course need a b The engine starts off quickly and quickly. After the engine has warmed up a bit in the stand and the engine gets calmer, it starts to glow strongly. The whole body starts to shake and shake (everything is still standing). As soon as I put in a gear, the jerking gets stronger and as soon as I go off the brake, it is soaked with a huge jerker. This is visually accompanied by a red light under the speedometer. T. (BMW driver should know the red light). Only after several attempts and a lot of gas in the P gear he starts to run. However, the jerkers remain unchanged. While driving he runs calmly and the engine is spinning joyfully and quickly. When I stop at a traffic light and go on the brake he starts to jerk wildly again. Now I lift my foot to step on the gas. As soon as I go off the brake and tap something on the gas on it a small pause occurs during the acceleration (short n When I’m on the gas), if I don’t give too much gas at this moment, it’s always interesting to start. That happens quite often. Often on a slope, but also on the flat road. I’m a student and unfortunately don’t have the necessary change for a professional but a friend as a mechanic (without carburettor Kentniss) and my littleness (no Kentniss at all). A few tips would be very helpful to what it might be and where to start the best Thank you very much in advance!!!!!!!!!!!!!!! PS: We have found out that the engine sucks in false air through a defective hose which we have replaced immediately unfortunately without success.
