346xp high idle

[sre09]

Hi. I have a 346xp husqvarna that idles way too high. I also noticed that primer bulb is disabled. Where do i need to look at?

Turn the idle screw clockwise till you get 2800rpm or nicely settled to where the chain don't move. Many people don't believe they need a primer bulb on a 50cc saw so they disable them, l would leave it unless you have starting difficulties. lf your idle won't come down by adjusting the screw, you may have bigger problems and need a pressure/vac test. lf that is the case it should not be run untill its repaired.

Some suggestions at the "bigger" issue;
-major airleak
-fuel leak
-faulty carb.

Hows the afjustment on the L screw? And throttle response? Could be your L screw is too far in as well.

First thing I'd do is replace the fuel line & filter. Fuel lines on these don't seem to last more than 3-4 years, especially if running E-10 gas.

Can you take a pic of what you're talking about? That would be very helpful.

This isn't the seal, it's the worm gear. Take a look at the intake boot, the one fixed with the plastic clamp are often leaking.

That's the seal. Does the crank have any radial play?

What do you mean by radial play?

 

[sre09]

Here it is another better view of seal and bearing

It should not have any side to side or in/out play/movement. If does, it needs bearings, but I've not run across a 346 with bad bearings and I've got a few of them with tons of hours.

Looks like a bad seal? Not hard to replace though.

It has side to side play but in and out doesnt.

 

[sre09]

I dont know if in video you can see but when i move the seal the bearing moves also.

Bad bearing then. Time to replace both crank bearings & seals.

Yep, that's a bad bearing.

Yep, that's a bad bearing.

I hope that only bearings and seals need to be replaced. Could be the case bad?
