what the hell is this noise?

[blsnelling]

Just don't pull the drum and leave the clutch, and then rev it up!

 

[whitedogone]

Sounds like a pos husky running to me....concider yourself lucky.

Engage the brake and see if it stops.

that was running with the brake engaged. no change either way. It's going to drive me crazy until I figure it out....

hi, did you find what was causing this? My chainsaw as the same problem..

 

[old guy]

I don't hear anything unusual for a chainsaw.

BTW.........I never step on my saws to start um................

Wait till you get older!

I have 40 plus saws, a lot of them do this, it's just the clutch drum ringing.

 

[Bob Hedgecutter]

Get better earmuffs- the noise will go away then.

 

[weimedog]

I've seen some of those where the crank wore at the bearing surface, clutch wobbles around.....makes a hell of a rattle.

 

[dieseldod]

Sounds ok to this duffer ,but I have abused my ears over the years .screaming detroits or bike motors I guess are the main culprits

It's the centrifugal weights, loose and rattling on the central clutch hub spider, my 550 sounds like this (mines much worse to be honest!) if you take the brake cover off you will see that the weights are loose on the clutch hub!

I'm 66 and I could still start my MS-461R w/o using a foot.

There is an old joke....put in the racial slur of your choice. Guy buys a new saw, comes back a few days later complaining it would only cut a cord of wood a day. Dealer says " that doesn't sound right " and starts the saw. Guy says " what's that noise" ?

 

[lone wolf]

Most stihls I've run sound similar. Never really bothered me. I just figured it's what they sounded like. Patina for the ears

Yep.

interesting, thank you, is there a fix to that (change clutch springs?)? Could you be a bit more specific on the problem thank you

 

[HarleyT]

One could just adjust the idle speed a tad.

The only thing to do if the weights are worn is to replace the clutch completely, as all of the components will be worn out.
Saw will be still usable for a good while like this, I've had clutch springs break but never had a clutch itself blow apart, the clutch drum is a different matter!!

 

[sb47]

Just run it. When it craps out then fix or replace.

Sounds like sticky valves.
