Common Carburetor Issues: How to Fix a Bike That Won’t Idle or Start
If your bike won’t idle or refuses to start, the issue could be your carburetor. There are several reasons why your carburetor might cause idling issues, from clogged jets to improperly set float heights. But don't worry—most of these problems are easy to fix with the right tools and expertise.
One of the most common issues is dirty carbs. Over time, dirt and fuel varnish can build up in the jets, causing a restricted fuel flow. This can make it difficult for your engine to start or maintain a stable idle. A carb cleaning is often the first step in fixing this problem.
If your bike is idling too high or too low, the issue could be with the idle screw or the float heights. When the float height is set incorrectly, the carb can flood, which can make the bike stall or have trouble starting. Adjusting the float height ensures that the carb receives the right amount of fuel, preventing flooding and idle problems.
Other issues could include worn-out seals, clogged needle valves, or a malfunctioning fuel pump. If you’re dealing with carb flooding, inspecting the carb for wear and tear is essential.
