Jonsered 2045 throttle, help?

[LAWN BOY]

The throttle worked before I took it apart to clean the carb. Now it only works if I hold the carb up so there's more tension. It also works without the carburetor in the bay. Is there an adjustment or something I need to do? It's linked how it was before removal.

Is the carb upsidedown?
I can't tell by that picture

It lines up with the af holder and fuel line, so no.

Ok
Take a bigger pic of the whole thing...

Does the throttle cable go into the lower portion of the carb plate? Which way does that plate rotate (from the position it is in the picture), clock wise for more throttle or counter clockwise?

 

[ErnieG]

Id think it rotates CCW with the idle screw the way it is but that's just a guess ...

I'm not certain about the first thing, I could try.
Counter clockwise.

Will do.

Yeah, I have had some carbs I have taken apart and when I go to put it back together, it went back different than I remembered (I have started taking pictures of tear downs).

I have not seen that saw before, but looking at the IPL, I am guessing the trigger pushes on the cable, if the cable was connected to the lower section, then it would push against the plate causing it to rotate counter-clockwise. That would be my guess. You might also take the handle apart and make sure the cable didn't slip out of its channel, if it has, then it might be giving you the slack you are wanting to take up.

I took the handle apart earlier and it became a disaster although at first the inside of the handle appeared to be functioning fine. I'll put it back together using that diagram. I also take pictures of projects, just not enough pictures lol.

Is your throttle cable ran like this ?

Slightly different and I don't see an idle screw in that pic.

I found a couple of views from videos, I think you were in the right place:



In the three videos I watched, they all had issues getting it back on correctly. I think the throttle cable goes opposite what I thought in post #8, which would then pull on the throttle plate causing it to move counter clockwise.

Looks like the idle screw was removed, there is the hole for it, but its not there.

Ya that's what I thought,

I have some of these saws but it's been ages since I worked on them. It's a bit tricky. @David Young @Spike60?
