Why does my chainsaw only runs on choke?
If your chainsaw only runs with the choke on, it is likely an issue with your carburetor. If the carburetor is plugged, the engine will be starved of fuel and will not run. However, if the engine is plugged, the choke will pull more fuel through the carburetor’s idle circuit and allow it to run.
Why does my chainsaw start and then stop?
The carburetor is a part that, when plugged or improperly adjusted, can cause your chainsaw to start up, but immediately die. Many carburetors have adjustment screws, and you may be able to use them to get your engine working properly again. A clog in the air filter can starve the engine of fuel and cause it to die.
Why does my chainsaw dies when I give it gas?
Because your chainsaw will idle, but dies when it is revved up to full power, it means that the filter is only partially clogged; it will allow enough fuel to the engine to run on idle, but not enough to sustain full throttle. If the filter becomes clogged, not enough fuel will reach the engine for it to run properly.
Why does my chainsaw bog down when I pull the trigger?
Without the right amount of air and fuel in the piston cylinder, the 2-cycle engine in a Stihl chain saw runs inefficiently and the saw loses power. When the saw bogs down during cutting, it’s usually the high-speed screw you need to adjust.
Why does my 2 cycle engine stall when I give it gas?
Fuel and Air Filters One of the possible reasons why your two stroke engine is stalling when revved is because of a clogged filter. Air filters rid the air of debris before it enters the engine and its intricate parts. This debris can clog and damage the air filter over time.
How do you fix a chainsaw that won’t stay running?
Vent in the Fuel Cap is plugged – If the vents in the fuel caps are clogged the fuel becomes vacuum locked. Check the cap and clean it or replace. High-Low adjustments screws may need calibrating – If you have these screws in your chainsaw, adjust them by turning both screws clockwise until you reach the end – gently.
Will a chainsaw run without air filter?
Don’t Run Your Chain Saw With a Dirty Air Filter But if you don’t clean/replace your air filter (shown here), the engine will suck some of that dirt and dust into the combustion chamber, causing excessive wear. If you notice a loss of engine power or excessive fuel consumption, check the air filter.
