Hi,

Just a quick one. As the title says I'm having trouble starting the saw, this hasn't happened in the past. Every time I pull the starer cord the de-comp valve pops out just under a third of the way through the pull then making it go really stiff and not pull any further. any advice?

Thanks alot :001_smile:

Hmmm. Even with the comp button (sissy button) out the saw should still turn over even be it stiff.

 

Take the plug out. Does it pull over well every time without the spark plug?

 

Hard to believe the comp would be that high for it to completely stop the saw turning over.

The decomp valve is faulty, you need a new one or you can use what we used to in the old skoool days, we called it a stronger arm.
