Just imagine you worked well with your Stihl chainsaw at night and in the morning when the heavy rain hit the garden, and now you are planning to cut down the different branches of the fallen trees with the saw. But the chainsaw ditched you at the very last moment and did not start even after several attempts. 

This must be very annoying even when you checked the fuel and did the choking, but nothing came to use.

You must be thinking about why my chainsaw will not start. Let’s dig into the matter and discuss the most common problems that can happen to the saw anytime, which can halt the starting of the saw smoothly. 

Why Will My Stihl Chainsaw Not Start 

When the chainsaw engine causes problems in starting up, the user thinks, why will Stihl chainsaw not start?

This could happen for several reasons, and the most common ones are; some fuel left in the tank, the air filter and fuel filter left unclean with dust or debris, problems with the spark plug or ignition coil, and many other such issues.

Common Problems With Starting Of Stihl Chainsaw 

Here is a brief description of some common problems that happen to the Stihl chainsaws, which prohibit the start of the saw.

Scrap Fuel

Fuel that was left in the fuel tank for several weeks due to saw being not in use for days or weeks because the user is just a homeowner or a local gardener.

This scrap or excess fuel causes blockage in the fuel line, which leads to the engine not getting started quickly. 

Damaged Spark Plug

The spark plug needs regular cleaning and replacements to remain functional. If a user does not change the spark plug for an extended period, it suddenly gets faulty and will not fulfill its function.

Clogged Air Filter

An air filter is vital as it provides the fuel with the required air, which should help the engine get started. The air filter also needs regular cleaning; otherwise, dust or debris can accumulate in the filter and block it.

Damaged Ignition Coil

The ignition coil provides a spark plug with the required voltage energy. If the spark plug is in good condition and has been replaced before but is still not working well, it means the problem lies with the ignition coil, which fails to provide the spark plug with the required voltage.

Primer Bulb 

Primer bulbs can get damaged, break, or diffuse, leading to problems with the starting of the engine. The damaged primer bulb restricts the fuel from moving to the machine, which causes further issues.

Clogged Fuel Filter

The fuel filter is like an air filter, which also requires cleaning and replacement annually. If these measures are not taken on time, then debris and dust can accumulate in the fuel filter, causing a halt over the start of the engine.

Flooded Engine

The engine can get flooded with fuel, which happens because of several tries of starting up, as fuel gets sprayed on the machine every time users try to start the cold saw. This fuel accumulation can drain out on its own, but it’s better to take measures to clear the fuel from the engine to resume the working of the saw.

Conclusion 

When users ask why will my chainsaw not start? They must be answered well and should know about the reasons behind frequent issues that happen with the engine. The article above discussed the reasons for the Stihl chainsaw users to understand the matter more clearly.
