Hello guys. I have a problem with a Husqvarna 236 chainsaw.
One day i wanted to fill up the fuel reservoir and surprise...all the fuel was leaking out. After investigation, i've discovered that all the fuel it's leaking through the air vent of the fuel reservoir. The Check Valve(Duckbill) and the Plug were pushed out. The Plug i didn't even found it again. I inserted the Check Valve again into the vent hole, but when i accelerated the chainsaw was pushed out again.
It looks like that it's some kind of pressure building up in the fuel tank(positive pressure). What are your thoughts about this? I will have to order another Plug. But i don't know. That plug it's like some air filter. It will help the Check Valve to remain fixed in the hole?
So, to be clear. The pressure in the fuel reservoir gets higher when i accelerate the chainsaw. In that moment the duckbill it's being thrown out.
It's funny. The air vent helps you to avoid negative pressure in the fuel tank. But, I actually have problems with the positive pressure. What its creating this pressure in the fuel tank?
