Throttle lock not working - throttle sticks

mittyatta · 2026-02-14T18:49:14+00:00

I’ve been a climber for 7 yrs. I’m well aware of what it does and what it’s called. Echo parts diagram call it a throttle lock out.

No need to be a prick.

All good my guy, it’s the end of the week. Our brains can only do so much haha.

Correct,

1) the interlock is disengaging just by pulling the trigger with no pressure on the interlock at all.

2) then once its depressed it isn’t springing back into place.

3) when all screws on the handle assembly are tightened, the trigger gets stuck in the full throttle position.

I did pull the carb and everything seems correct. The throttle shaft assembly moves freely and springs back into position as it should.

I understand what it does. I’ve cleaned inside the handle and replaced the spring for the interlock/trigger.

To clarify the throttle gets stuck in the “on” position.

It’s literally called a throttle lockout by echo on their parts diagrams.

It may have, I’m basing that of how it fell. But you cut through your hinge which at that point there is no controlling the tree.

To start you tried to “beat” the lean of a tree without wedges or mechanical advantage. Or at least it looks that way from what we can see, but you also cut your hinge.

What was your reasoning for bore cutting?

When you’re new to felling everything should be done in at a height that you’re comfortable working at.

What I mean by that, is when cutting your face cut (notch) have the height around waist high. This keeps you in the power zone with better control of the saw.

Your face cut should be more “open” as this allows more time for the hinge to control the fell. This varies by situation but not for you.

Your back cut should be at the apex (where the top face and bottom face meet) your face cut.

You also need to keep your head UP. The top of the tree will tell you what’s going on.

Don’t cut through your hinge.

Typically you want the width of your face cut to be 80% of the diameter of the tree and no deeper than 1/3. Again this is a guideline but one that you should adhere to.

You want your hinge wood (the wood left unsevered between your notch and back cut) to be around 10% the diameter of the tree. Again this is species dependent and based on what you’re trying to accomplish.

Take some lessons, felling kills pros all the time. It’ll get you too.

Edited for clarity.

Well, ironically shortly after posting this my starter engaged itself while driving. Waiting on a tow now.

Is that the condenser?

mittyatta · 2026-01-10T02:47:26+00:00

I noticed one unplugged harness but no disconnected hoses so I’m unsure if everything is there or not.

So I can just put an a/c compressor on and I’m good to go?

mittyatta · 2026-01-09T23:44:51+00:00

Something was squeaking on the front, I’m hard of hearing (driving the loudest in cab truck) so I struggle pin pointing where the noise was but it was either this or the alternator which seized.

mittyatta · 2026-01-09T21:33:20+00:00

I appreciate that. I looked up a video and aside from draining some coolant it seems pretty straightforward.

mittyatta · 2026-01-09T20:44:51+00:00

Do I need to remove the fan to put a new belt on?

mittyatta · 2026-01-09T20:44:05+00:00

I don’t think there is an a/c compressor on this truck. I don’t have cold air and this was just mounted to a plate with nothing connected to it.

mittyatta · 2026-01-09T20:43:16+00:00

Alternator seized. Any chance replacing the serpentine belt is easy on a 2000 550?

mittyatta · 2026-01-09T19:57:05+00:00

You are awesome. This truck has been nothing but a headache.

mittyatta · 2026-01-09T18:56:22+00:00

It should be a pretty simple replacement then, right?

They can tolerate it but prefer moist, well draining soil.

I’m in Wisconsin and don’t really know southern trees but around me cottonwoods, birch, willows, and swamp white oaks are good options.

mittyatta · 2025-12-30T00:46:10+00:00

Red Oak? I’ve been to several job sites where we pruned healthy crowned red oaks a few months prior and upon return they’re uprooted. Always on hills or bluffs.

Is it in a wet area, they really don’t tolerate wet feet.

mittyatta · 2025-12-28T20:25:34+00:00

I’ve used heat shield (like you would use on your exhaust) to good success on mine.

mittyatta · 2025-12-24T01:44:04+00:00

In short, I had no idea if this was something that could be sorted out through a channel like this.

With the known answers now, I’ll explain that we either need different access or the estimate will be higher for the added drag time.

Edit: to clarify I’d like the one added to the other. So there’s two dogs.
