Unhappy carburetor

I have 1988 model 200 which was imported from Germany as a second hand vehicle.For the past month or so whenever i shut the engine after a ride it get off with few jerks in the engine as if there is a missing. The guys here dont know head or tails about it. They said the problem is in the Pre Ignition. Will the problem change if i change the carburetor? Plese help .

From what you described it sounds like the engine keeps trying to run after you have shut it off. I think the ignition timing is off and needs to be checked/reset.

Try running some high octane gas first.

Yeah, sounds like pre-ignition. This is caused by something in the combustion chamber running hot and igniting the fuel even without a spark.

The usual causes are poor octane fuel, ignition timing over advanced or carbon deposits.

This is less of a problem with injected engines as the fuel supply shuts off when you turn off the ignition supply.
