sticky switch on the 044

[JIMG]

In winter everything is a little harder to do and hurts a little more, little things tend to be a bigger deal. I notice I tend to leave my 044 behind simply because the switch is so stiff on it. With gloves on I have to use the scrench to force the lever down. It finally aggravated me enough to take it apart and grind a little here and there, smear a little grease on things. Still no love. Any suggestions? Should I just get another assembly?

Is it all oem, no aftermarket parts?

Definitely not normal by any means, you'll have to find the bind to come up with the solution. Start by removing the cover to gain a visual on things.

All oem. red lever. It's the only 44 Ive ever run. I was curious if this might be a common issue with perhaps a well known fix.

Reason I asked was I had an 046 with an aftermarket filter base that had that issue. Had to do some filing and grinding..

I'd get it apart, there should be some rub or witness marks where it's binding I'd think.

Could give it a coating of blue chalk line chalk, install it, work it back and forth a few times and see if that shows the problem spit.

Like Ed mentioned, it could be the filter base interfering. The switch shaft uses an alloy "finger" in the switch box which rides on a fairly stiff spring in the PTO end of the switch shaft. Sometimes fine sawdust will build up in the switch box (or under the spring in the switch shaft) and makes it tough to operate the switch shaft. Try cleaning all that out real good.

I would check over in that box on the right hand side

Been a minute. But yeah, whatever that MC lever goes into over on the right hand side

That's what it was. That contact spring visible in Ed's pic. (1128 442 1601) First I pushed it in to conform better to the plastic housing. That made it worse. bent it out at the bottom and bingo, smooth. Easy little fix.
That stiff switch had me pissed out in the woods.
Thanks for the inputs.

Now you can go back to using it vs leaving it behind. Good to hear it's fixed

Welp, since i had the saw up on the bench I decided to do a bit more after the switch fix.
Since the muffler was opened up some the idle likes to dip and die when the saw is tipped down. Case passed Pressure/vac test, zama is cleaned and rebuilt. New impulse installed, intake boot passed inspection, new fuel line, fuel filter.
I see there is a very prominent lip on the intake where fuel is probably puddling. I can grind this off but I am wondering if this is going to change the intake timing in a bad way.
