Carb adjust screw - limiter caps

[thegasman]

Hi all,

 

New to this chainsaw business.

 

I have bought a Husky 351, which was running pretty well initially. I made the mistake of giving it a really good clean, including the filter, and now it's over revving, and the chain runs at idle.

 

If I adjust the T screw out, the saw stalls before the chain stops spinning.

 

So, I think by cleaning the filter the engine is lean, and running too fast.

 

However, on trying to adjust the L screw I've found there is a plastic oojamaflip thingy with dogs/ears/tags/whatever you want to call them limiting the adjustment I can make - so I'm not sure that I am really setting the screw at L=1. Same thing for the H screw.

 

Any tips? Much appreciated.

The T screw is tick over and if you screw it out it will stop it ticking over. The H & L are set at what they think is optimal before the caps are applied and then any adjustment you can make is limited by the cap. Try turning the T till your saw ticks aver then turn the L anti clockwise to richen it a bit although it does sound like you have disturbed something cleaning it to cause the problem you are having. Did you catch the choke linkage when you removed the filter ?

Chains spinning ??usually a fraction of a turn out on the L jet clears this.

Ah. Just took the clutch cover off, one of the springs in two pieces! Wasn't the case when I last checked but must've been on the way out.

 

Will take the saw in when I go get a replacement and get the guys there to check the screw positions, which I think I have adjusted properly.
