MS440 start up problem

[Jack.J]

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

Try replacing the valve

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.

[Jack.J]

yes, it pulls over every time when the spark plus is out.

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.

Have you tested the compression?

Just change the decomp valve - been pulling over an 084 today and not using the decomp, not quite as bad as a 076 or 298 Husky but the 460 should pull over reasonably easy but depends on your build and strength.

 

Easy enough job but long reach sockets make the job easier:thumbup1:
