If the car suddenly starts vibrating, sneezing, jerking, or stalling, then the search for the cause should start with the carburetor. And it doesn't matter if you have a Solex or Weber, both are considered capricious. Timing belt breakage. We have often heard about the belt breakage on these power units. Usually, owners who do not monitor the condition of the timing belt are to blame. Despite the gaps in the pistons, valves bend in 100% of cases. Overheating. Thermostat sticking often leads to engine overheating and block warping. You will find out about this when the cylinder head gasket burns three times a month. Nothing can be done, only replacement.
