Intermittent sputter on gas g16

[UMPIREBIGMO6]

My friend has a 2000 g16 that has a sputter (miss) when trying to run slowly (half throttle) the cart has a new fuel pump, filter, and new lines installed. Fueltank is clean. Uses non ehtanol fuel as well.also carb has been cleaned and the electrical system has been checked. All ok. The problem seems to occur whether cart engine is cold or hot. If cart starts to sputter, if you push accelerator to floor it seems to make it go away? It doesnt do this all the tme, just periodically. It may run for 3-4 rounds before it does it and it may do this for 1-2 rounds and then clear up??? Any suggestions?

Since the problem persists whether the engine is cold or hot, and pushing the accelerator to the floor seems to temporarily resolve it, it's likely that the carburetor is still not clean enough and/or the intake is not sealed up completely. A carburetor's primary function is to mix air and fuel in the correct ratio for combustion within the engine. When you press the accelerator, the carburetor allows more air to flow into the engine. Simultaneously, the carburetor draws fuel from the fuel tank and atomizes it into a fine mist, mixing it with the incoming air. This air fuel mixture then enters the engine's cylinder for combustion, powering the engine.

If the carburetor is not clean enough, deposits or fine debris may obstruct the precise mixing of air and fuel, leading to inconsistent engine performance, such as sputtering. Similarly, if the intake is not sealed properly, excess air can enter the engine, disrupting the air-fuel ratio and causing similar issues. In the case of pushing the accelerator to the floor temporarily resolving the problem, this action likely floods the engine with additional fuel, compensating for any deficiencies in the air-fuel mixture caused by carburetor issues.

I'd suggest replacing all gaskets and making sure that the intake is completely sealed. Additionally, purchasing a rebuild kit for the carburetor and having it sonic cleaned at a lawnmower shop might be beneficial. Sonic cleaning is a process that uses high-frequency sound waves to agitate a liquid solution, effectively removing dirt, grime, and other contaminants from hard-to-reach areas of the carburetor. This method ensures a thorough cleaning without damaging delicate components.

If the carburetor is not OEM, buy one. Aftermarket carburetors are often of lower quality and may not be properly tuned, making them less reliable than original equipment. While sometimes more affordable, aftermarket carburetors frequently lack the precision engineering and quality control of original equipment. These carburetors arrive in a generic state, requiring adjustment or tuning to match the specific requirements of the engine they're intended for. Unfortunately, this tuning process may be incomplete or inaccurate, leading to suboptimal performance and reliability. In contrast, original equipment carburetors are designed and calibrated to meet the exact specifications. They undergo testing to verify they deliver consistent performance and longevity.
