McCulloch Chain Saws

[nallac]

Pm850's......I wish shipping costs weren't so high,i'd chuck my near mint PM850 Super (with a cosmeticly(SP) mint condition piston scewed spare 850super)on the bay and see what i could get......Heck i only payed NZ$140 for it..about US$114


Finally got around to playing with my 7-10a today,I stripped it down and checked the piston last week,it all looks good.
Thought i'd chuck a carb kit in it before i reassembled it.
Got it all back together and took it outside for a play
It was a b*&ch to get started.....didn't want to idle,it would rev out nicely but bog down off idle.It would idle for a few minutes then die,20 pulls later it would start......
Spent about an hour messing around with carb settings before giving up and grabbing a spare carb i got in the 700 barrel parts. Chucked that on,didn't even clean it,second pull it fired....
Pirated the 24" b/c off the Pm700 and cut up a few noodles...

Man these things have some grunt.....I'm happy now.

Use lots of carb cleaner when rebuilding a carb. I always set the H and L screws out 1 turn when starting for the first time. Set the idle pretty high, and you can lower it later. Don't give up - you will get better at it.

Hey Warped5! Lets see that puppy .

Not his, but who cares!

Here's little brother

This 450 needs some loving. Crankcase cover assembly is cracked beneath the flywheel, needs a recoil replacement and the tank is cancered up

I did skip the carb cleaner part..blew it out with my compressor,I was in a hurry to get it done before dark.
I also set the H&L screws at 1 turn out and had the idle maxed out.
Just thought it abit strange a carb i had laying around went on and ran good.
i need to pop out the little caps(another step i bypassed) and give it a proper clean and try it out on the PM700(its carb needs going thru).
Any tips on getting the little suckers out would be appreciated.

I would reccomend soaking it in gas or some type of solvent first and then blowing it out before you get into drilling out the welch plugs. There is a outline on how to do this in the 10 series shop manual as well as the Walbro SDC manual.

You could have something clogged/gummed up in there, if you put a known working carb on there and it ran fine obviously this one has an issue somewhere. Get it cleaned out proper before possibly doing some unneccessary labor.

Those saws are tanks! That S550 has some snot behind it.

I would not part with that kind of coin if the saw did not have a NOS (or original) bar ..... and needed repair? Come on!

Makes me wonder what my Super 550 may be worth on feeBay .... :msp_ohmy:

Hey Warped5! Lets see that puppy .

Yea man, let's see T-Rex and Brontosaurus. Or are you too scared to get them out of their hiding spot?

Thanks Thiery. This is the hot thread today.

Kinda busy just now, border skirmish. I think its a diversion, the invasions usually cross the river to the west.

Nothing like waking up and going straight into the subject of yellow saws.


Did you get my PM the other day? Feel free to drop me a line in about 30 minutes.

I did get it, thx, been living the night life, getting behind. I'd ring you up, at work, insert fat frowny face of boss.

Not diversion, pinchers attack, where the heck did all those troops came from, dammit!

 

[HeRoze]

Thanks, but I don't believe there is a local bearing house in my small town. I was never able to find a source for 10 series seals so I have taken my chances with NOS purchases - it bugs me to buy an old rubber part. Remember your fuel line experience. Ron

NOS will work fine. That may get old after a few radial shaft seals, though. Also, since these things are made of rubber, NOS runs the risk of being old, hard, and worthless especially if they have lived the last 20+ years in the back of some hot out building somewhere. did you check out the seal links I sent with the ability to find your own Timken p/n's? once you have the p/n, your small town is no longer a factor.

I will pull them out today and post the pix. I am away from home most of the day, but be patient ..... :msp_smile:

You sent a link? Didn't get it if you did. Thanks, Ron

Pix - POSTED!

Here we go fellers, I have not touched these since picking them up 10 days ago. The Super 550 has a 30" (maybe original) bar and the Super Pro 81 has a 24" that is probably not original. Enjoy! (Chris, the wife was over at the MIL's house)

First, the siblings together ...

The Super Pro 81 ...

The Super 550 ...

Braggart!



I would be also.

 

[RandyMac]

All Warped needs is a good 10-10 to fill out a three saw plan.
(the 610 don't count:hmm3grin2orange

RandyMac and Thieroff put me up to it .... I hadn't intended to post pix until I began work on them, like the 610.

A 10-10 would do the trick.

If your wife isn't allowed to see them neither are we, huh?




Nice saws man!

Another man fallen victim to Yellow Fever.


Chris

 

[RandyMac]

The Fever knows no bounds, nothing like it.
I remember running my first yellow saw.

Dammit Randy, don't just leave it at that.


Elaborate.
