Columbia Engine Parts

This carburetor is a genuine OEM part. It is compatible with MTD brands, with models including 270-SUA, 370-SUC, and 170-SU. It can be used on appliances with small engines such as lawn mowers, snowblowers, and wood-chippers. The function of a carburetor is to combine the air and the fuel before the two are filtered into the engine through its connecting valves.If an engine or an appliance altogether is malfunctioning, it could be a sign that the carburetor needs to be replaced. First, check to see if the tank of fuel is in fact full. Then, in order to isolate and test the efficacy of the carburetor, tip a spoonful of fuel directly into the carburetor and try to start the engine with the starter rewind. If the engine sputters but eventually stops, it is likely that the carburetor is damaged or needs repair. This can be solved by ordering an OEM replacement carburetor part. Remember to always wear gloves when handling, repairing, and operating outdoor equipment.When searching for a replacement carburetor, it is important to corroborate and confirm that the appliance and engine are of the MTD brand.

Pistons are essential for proper engine function. When expanding gases push the piston, it turns the crankshaft. When the piston compressed the fuel-air mixture, the spark ignites and causes combustion. If the pistons are going bad, owners might notice white or gray exhaust smoke, low power when accelerating, loss of performance, or excessive oil consumption.Pistons may need to be replaced for any number of reasons. They could have damage to their crown, which could be caused by overheating. There could be impaction marks if they were not installed correctly or if the valve timing is incorrect. The pistons could be fused or have elements that have melted, or there could be cracks in the piston. Any of these issues would necessitate a replacement.This piston is used for select small engines from MTD, Troy-Bilt, Yard Machines, Columbia, and Cub Cadet. Each piston is sold individually and is a genuine OEM part sourced from the manufacturer. Those who need to replace more than one piston will need to buy them separately.
