This rusty W126 280CE has been parked for 3 years without running. How do you get a car starting which has been idle for so long? The full story can be read here: https://mercbenz123.com/posts/starting-long-sitting-car/
The video of actually starting the car is shown here. Getting it to start was a bit of a hassle, but when it started it ran totally fine. Notice the normal idling of the M110 engine after start, no fuzz even though the ignition system here is totally worn out! The last time this car was driven the engine barely could run on idle due to worn distributor and ignition wires. Mind this is many years ago, and the car is scrapped due to heavy rust. The engines still lives, 333.000km.
