Does anyone know why the K10-HDB kit has two gaskets that look the same but one is rubber the other is normal gasket material? The carb only has the rubber one when I took it apart.

Do I just use the rubber one and ignore the other one assuming some HDB carbs use that one instead?

Given the 10% ethanol in most gas, I'd be using the normal paper composition gasket if they are identical. B.W.D.I.K.;)
 
As long as it fits the fuel line tight it will work.
I try to use the old style aluminum with the felt
filter because they are heavier and will stay on
the bottom of the tank.

I hear ya but it seems like the felt stuff just plugs the carb. Both my 70E and my PM650 clogged because of this. I have been putting the new style husky filters in most things but this PM650 has a huge fuel line. I did find a similar fuel filter at chainsawr that I might try...

They appear to be the same thickness but different materials. Who is Fish?

Is there a filter for this larger fuel line like the nice solid Husky ones but with a larger barbed connection? The carb is full of the felt from the old fuel filter so I need to upgrade.

Fish is a highly respected AS member known for his sage-like wisdom.

Husky fuel filters fit a 3/16 line. Pick up a replacement filter for a Stihl. They use a 1/4" line.

PM sent to Fish, thanks for the tip.

I am on the Stihl filter thing like white on rice...:hmm3grin2orange:
 
SOS 125 clutch bearing

My clutch bearing is split on my 125. Is there any interchange with a Stihl or Husky? Ten series is too small! Got more wood to cut tomorrow - plus 36" .404 bar came today. Thanks, Ron
 
I am flattered by the honorable mention, most carb kits have more gaskets than you will use, and as a rule, I replace the gaskets with the like kind,
and being on the fuel pump side, it is not that critical as long as it seals,
so just put it back like you found her...
 
I had 7hp of Monster Mac fire up kind of unexpectadly today!

But then found the leak again :cry: Good news is, I can tear down the 7-55 down to the block in about 20 minutes. haha
 
125 36" MAC bar installed

Still need a clutch bearing, but I put on the new 36 inch MAC bar & MAC chain anyway. Looks better than I was expecting. I took a picture because it'll never look like this again. In one week, the price of this bar (no chain) when from $85 plus $35 shipping to $195 plus $35 shipping. I thought $85 was high, now I wish I had asked if he had two. Ron

Hey, that really spruces up that ol' SP. Lookin good.

If that guy goes much higher, there better be a power head attached to those bars.:dizzy::dizzy::dizzy:
 
Heavy old saws???

Unless there is some cheating going on, where is the lighter modern day equivalent to the 125?

SP125C 123 cc, 23#, 48 oz. fuel
Stihl 880 121.6 cc, 22.7#, 44 oz. fuel
Husky 118.8 cc, 22.9#, 43.2 oz. fuel

The Husky has a shorter stroke but a working rpm of only 9000. Doesn't the 125 work at about this same speed? Don't have info on the 880 so I can't compare it.

Only improvement, I see on paper is electronic ignition - which I can convert to if I want.

Just thinking out loud as to a proper response to the critics of old metal.

Stinkbait and I were discussion the 125 vs the 3120 at the last GTG. He said it looked like the 125 was outcutting the 3120- both with 36" bars buried in white oak.

The Husky is pretty rich though.

Id pick the Mac over the Husky any day. But I have the 3120 haha.
 
Not a PM605

After agonizing over a PM 605 for a couple weeks I bought a dog eared 10-10 (model 60002U) at another pawn shop literally accross the street. Basically a sound, good running saw but oh soo ugly. Bar and chain is shot. Picked up a 20" b&c at Menards. Walbro SDC carb......:clap:

Questions:
I 'back flushed' the oil soaked/sawdust caked air filter with brake cleaner. Good enough? Hot soapy water safe?

Do the fuel and oil caps get 'O" rings? They both leak.

Is clutch nut R.H. or L.H. (both type are listed on the IPL)? I want to clean the oil off the friction surface.

Are the bar plates required (P.N. 64330) ? None are present. It has a "rim sprocket'.

Why does the bottom of this thing look like they used it as a snow board on the driveway without the benafit of snow.:cry:

Thanks fellas!

Need to get this thing shaped up. Fraternal Order of Police lodge hall has two large pines that need to come down. Gonna need a bucket truck on the one.

Will do, thanks for the reply! :cheers:
 
ok

Questions:
I 'back flushed' the oil soaked/sawdust caked air filter with brake cleaner. Good enough? Hot soapy water safe?

Brake cleaner will probably dissolve the adhesive holding the flocking material to the screen. Is the screen itself visible? If there are just a few small bald spots you can put a dab of silicone sealant over those areas. Diluted purple cleaner works well for cleaning filters. If the filter has obviously seen better days (i.e. looks like a screen door), then just replace it. There were several styles of filters used, all are available. Back in the day, a lot of filters were cleaned by swishing them around in a clean container along with some 2-cycle mix. Then the filter was allowed to air dry before reinstalling in the saw. The oil from the mix helped the filter trap very fine dust. (Note: You do NOT use the mix used for cleaning the filter in your saw!)

Do the fuel and oil caps get 'o" rings? They both leak.

The fuel cap uses a cork gasket. The oil cap does use an o ring. Some of the oil caps are solid. The saws these were used on will have a tiny hole drilled into the oil tank along with a very small cotter pin inserted into the hole to serve as a vent. Most of the oil caps are vented by means of a tiny rubber duckbill valve set inside the cap. Look at the underside of your oil cap & see if there is a round opening in the center of it. Don't know what kind of material McCulloch used, but they seem to turn into some sort of sticky black glob. I have a couple of NOS caps that the duckbill valve has literally melted without ever being exposed to gas or oil.

Is clutch nut r.h. Or l.h. (both type are listed on the ipl)? I want to clean the oil off the friction surface.

Should be LH on a DD saw. Grease the clutch bearing while you are in there.

Are the bar plates required (p.n. 64330) ? None are present. It has a "rim sprocket'.

The bar plates should be used. They help protect the bar pad in the event that a chain is thrown. They also help provide a better seal between the oil outlet located in the bar pad & the oil hole in the side of the bar.

Why does the bottom of this thing look like they used it as a snow board on the driveway without the benafit of snow.:cry:

You should ask the original owner. Maybe they just couldn't wait a minute longer for the snow to arrive.



The saw might have been stored on a concrete floor and/or a damp environment. I was looking at a 10-10A one time & the seller was trying to start it up. The seller pulled & the recoil spring did not retract the rope. The seller then literally flipped the saw on to its side on his asphalt driveway & slid it around to get a better look at the recoil. Some folks either don't know, or don't care, or both.


Thanks fellas!

You are welcome. Have a nice day.

Need to get this thing shaped up. Fraternal order of police lodge hall has two large pines that need to come down. Gonna need a bucket truck on the one.

Don't forget the coffee, the donuts, & some spare sharp chains.
 
Great post Urbicide. Definitely don't forget the coffee and donuts. Actualy, if it's an F.O.P. lodge hall, they'll have plenty of coffee.............and something stronger on scene already. Bring donuts or BBQ...:cheers:
 
I took a CP55 down today, direct drive RH start saw but the clutch nut was normal RH thread. It doesn't help until you get the nut off but my experience is if the clutch has a key the nut will be normal RH thread.

Most of the clutches with a LH nut will have some kind of arrow indicating which way to turn to loosen.
 
10-10 gas cap seal

Thanks Urbicide

F.W.I.W.: National 'O" ring #622724 makes a fair gas cap seal. (Thanks Dad for passing down your 'O' ring kit.)

Off to browse evilbay & the vendors for parts.

S.I.L. is FOP lodge president, daughter is sec. Hard to say how this pine/fir tree thing will work out.
