McCulloch Chain Saws

Picked up another 5-10 Full Wrap

Just picked up this 5-10 saw with the full wrap handle. This will be my second 5-10 with the full wrap handle. Can't wait till it gets here.

I saw that on Mitchell and put a token bid in just in case nobody else noticed it.

Have fun.

I have located a shop in town near the plant where I work that does custom tube bending. One of these days I going to take the full wrap handle off my 5-10 and drop it off there, see what they come up with for a price on making duplicates.

I looked into this one other time with another AS member but the shape they came up with wasn't quite right.

We'll see if this works out any better.

I went out and ran her again... and the saw dies if I turn it on either side, or bar down... what do I need to look for now?

I think the carb settings are good now, as there is a nice popping idle. growl growl pop growl pop growl growl pop pop growl, kinda like that... there also is fuel in the carb box, again... I think I need to put more teflon tape on the fuel line where it enters the carb box. I really wish there was something to cut around here other than wimpy little pieces of firewood... I really want to bury thie puny 20" bar in some poplar or something.

I have a Stihl 045 that likes to die on it's clutch down side, which is indicative of a air leak. My homie 5-20 will die when tilted in any direction but it has weak diaphragms in the carb. As for the fuel in the carb box, are you sure fuel is not splashing out of the carb? I have a 10-10 that loves to spit a little fuel right out of the carb, especially during WOT but also happens at idle just not as much.

$90, almost worth it for the bar.

I was thinkin' the same thing. Money's "committed" to too many other saw and non-fun things already though. I'd sure like to have that bar, as I may be getting an SP81 localy soon.

I have a 36" -.404" used bar for these saws if someone needs one. Trade you for a "big mac bar" or?

I don't have any spare "big mac" bars to trade you of that length. Heck.............I don't have any of that length for myself. I do have a couple 30-31" length 'big-mac' bars that are staying with me. Got a 20" or so 'big mac' hardnose I'd trade for your bar..........but I doubt you'd be game. Maybe partial-trade?

I have 2 30" bars on my homies...1 roller and 1 sprocket. Both take 94DL of 404

Thanks Rick! Saves me having to drag out that XP1020 in the rain (shop's down the hill) and count all them drivers. That number sounds like what I counted on it six months ago.

I did exactly the same thing in that auction Mark! Made a 'token bid'.......both to see if I could get really lucky, and to keep track of the auction without using up my 'watch list' space...:msp_thumbup:

 

[promac850]

610, Did you put a kit in the carb befor you put the saw back together?

Nope... probably should have. I did take it apart and clean out the screen and passages. Guess I will look at that if the saw continues to give hints of running trouble. So far, I still need to tune it so it doesn't stall when I tip it on its side. I will be sure to update the saw's progress on running tomorrow.

btw, the handle insert came in today. I put it on the saw, and it already is much more comfortable to hold. Between the nice cushioned front handle bar from Mark and this rear grip that I reeled in off of fleabay, I will have no problem cutting all day.

The bar should be in next week...

I forgot some saws like to spit fuel out of the carb... thanks for reminding me.

I did not notice the fuel tank level going down abnormally like it was before. I.E. bar stool work chair covered in gas... We will know for sure tomorrow whether it leaks or not, as it will be sitting overnight with fuel in the tank.

I didn't know that you were bidding on it Mark. I put a friendly snipe on it the day it came on ebay. I would have paid $40 just for the wrap bar. I figured that it was going to go pretty high when I saw the price a couple days from its end time. I did see a pm700 the other day that had a full wrap handle on it and it was actually a different style. It looked more like the ones that you see on the av 10 series saws, but was shorter to fit the regular non av style 10 series saw.

Are you saying that the AV full wraps are hard to find?

 

[promac850]

Are you saying that the AV full wraps are hard to find?

Apparently. I saved the broken one I had and got it welded up so it was saved from the scrap bin. It needs a grip though. I just can't bear to waste something salvageable anymore... I made a few mistakes in the past with perfectly good items and came to regret throwing it away. Still haunts me to this day.

I'm thinking if I dipped the old saw tank in muriatic acid and got the white death off, I could have the hole welded up... but I don't know if muriatic acid is the best way to clean a magnesium part off. I want to save it nontheless, as the welding services are free. Or is the white death impossible ot get rid of?

 

[wendell]

I second that, it is possible. My wife won the 10K prize on that show when the boys discovered a tampon in the back yard and came running up to her thinking it was dynamite.

I saw that episode. That was really funny!

Well, I finally have something I can post in this thread. Maybe a little too rough for a first project but I guess i will learn a lot.

No. I'm saying that the non AV full wraps are hard to find.

 

[promac850]

Welcome to Club Yellow Wendell. Good to see you here. You now have the lead, a few yellow saw advantage over me... but that will change soon!

Yeah, start with the 70, it looks like it's almost ready to run.

 

[promac850]

I think the full wrap I have left over will fit on that Super Pro 70... am I right RandyMac?

If I am, I would be happy to send it to Wendell... it'd have to have some kind of grip put on though.

 

[wendell]

Yeah, start with the 70, it looks like it's almost ready to run.

I don't know if the 70 even has a problem. The guy I got it from said he accidentally put his "Stihl gas" in it and it stopped running but the compression is decent so going to get it cleaned up tomorrow and see if it runs.

The 1-50 seems to be the one I'm going to start with. It is the one that seems to be in the best shape.

Ah... 'stihl gas' 50:1 or 40:1... way too lean for these saws. It's possible that it needs some work. Hopefully it doesn't need more than a fuel filter or something.

I don't think so Lads. Whatever stopped that saw from running...............it wasn't because the gas/oil mix was 'way too lean'. McCulloch had been advocating the use of their brand of oil at 40/1 (and advising 'other' oils be mixed at 20/1) LONG before that SP70 was sold. The 'two ratio' recomendation was to make sure some yahoo didn't burn up their new McCulloch when running 30w motor oil in their mix. Any good quality modern oil mixed at 40/1 or 50/1 would not damage these saws. I run 32/1 in my old saws............but that's mostly just out of habit.

He probably put bad gas in the saw. It just happened to be an old/bad can of gas that he mixed for his Stihls. That's the only way the saw could have been damaged by the gas. Water contamination. Varnish. Crud clogging the carb or filter. You get the picture.

Accidentaly running gas with oil mixed at 40/1 or 50/1 when the saw had been tuned for 20/1 mix would only make the saw run a bit richer (meaning fuel/air ratio). That's because the 'thinner' mix is less viscous, and flows through the metering sections of the carb faster. It also contains more gasoline in a given volume, which means that the effective air/gasoline ratio would be richer. We've discussed this at length in other threads. If you feel the need, I'll dig up a link or two for you. It's also been discussed at GREAT length in motorcycle and snowmobile tuning forums. In any case, the saw wouldn't suddenly run so rich that it'd die.

Ah, I stand corrected. You may hold me still so RandyMac can smack me. :beated:

As for Wendell's saw, I really hope it just plugged the carb and fuel filter. Quick test for you Wendell... hold the starter rope handle and carefully remove your hand from the front handle bar while just hanging the saw by the recoil handle... if it hangs there for a few seconds, compression should be good. Remember, the bigger the cc's. the longer it will hang... so don't think the hang time for a PM610 should be the same for a PM850. 60cc will not hold as long as 80cc under similar weight.
