Running too rich, timing off. Search your engine and "backfire"
Please restate the question including more details about your symptoms.
Strip the carburettor down, soak the parts in carburettor cleaner, blow out all orifaces with filtered compressed air.
Follow the intake air plenum from the air filter. It connects to the carburetor. The carburetor is mounted on the intake manifold.
Fuel filter. Also use compressed air to blow out the fuel line to the fuel rail if FI equipped. If carburetor take the fuel line off at the carburetor before attempting to blow out the line.
unhook it from both ends and blow air through it Disconnect the line at the carburetor. REMOVE THE FUEL FILTER. Blow air through this portion of the line. If possible, remove the line at the fuel tank and plug the outlet in the tank. Now blow out the line between the filter and the tank.
It means to "go down" on the carb. Just put you lips on the carb "and blow"!
it either needs new rings on pistios or one piston is cracked causing blow by or ... blow by is when compression escapes your piston..
Surging is the result of a "lean" fuel mixture, meaning too much air and not enough fuel. The problem is most likely a dirty carburetor or an air leak in the intake system. To fix, inspect the carburetor and intake manifold for cracks or looseness. Tighten all fasteners to ensure all seams are airtight. Clean out the carburetor with some carb spray and blow out all holes/orifices with compressed air. If problem persists, carburetor must be removed and disassembled/rebuilt.
probably a head gasket.
why does ac blow warm air? why does ac blow warm air?
A carburetor mixes air and fuel in appropriate proportions. Air and Liquid fuel are the inputs to the carburetor at different points of the carburetor. Due to suction created by the working engine , atmosperic Air is accelerated through the venturi in the carburetor. Accelerating Air sucks Fuel into the venturi at its center from a level regulated liquid fuel pot in the carburetor,due to the venturi action. (Bernoulli's Principle) During the process of sucking the fuel is atomised /becomes a mist , as it enters the venturi. The atomised fuel then evaporates and mixes with the air uniformly. This uniform gaseous mixture of fuel and air is the out put of the carburetor. This gaseous mixture then enters into engine cylinders for combustion.
