Why won t my vehicle stay running?

Check to make sure your spark plug wires or ignition coils are seated properly on each of the spark plugs. A detached or malfunctioning spark plug wire will cause misfires and often a stall as the engine struggles to stay running on fewer cylinders.

What should I do if my carburetor is not working?

If the engine is not running right, the carburetor is the last thing that should be checked before blindly tearing into it. Ensure that compression is up to par in all of the cylinders, the valves are adjusted to their set clearances and the ignition system is operating properly.

Can a blocked exhaust system cause hard starting?

This can cause hard starting when hot, as the fuel will have boiled out of the float bowl. A blocked exhaust system can mimic carburetion problems due to the lack of power, but the loud hiss from underneath the car from exhaust gasses trying to escape is the giveaway.

What causes a carburetor to block the exhaust system?

If the needle of the vacuum gauge slowly sinks towards zero, there is a blockage of the exhaust system. Some engines, over a period of time, can have the heat passage under the carburetor become completely blocked.
