McCulloch Chain Saws

[Todd Loosli]

Thanks for the help and encouragement. I'll get it ripped apart soon so I have a better idea what questions to ask. You guys are like the poulan people, very nice but a different color of saw

Hey Todd seems I'm not the only green guy with a yellow saw.

Well I have it apart, wasn't to bad once I figured out how to unhook the trigger.
It's a dirty little thing.

I use puppy pee pads to work on cuz they soak up the oil and they are cheap

Looks about right.

Yes,it's amazing how much crap can get into such a little saw & the places where it can find it's way too.Lol

I need to find a repair manual if they made one

 

[edju1958]

Go on the Beg for Manuals thread,maybe they can help you out there.

Repairs are fairly self-explanatory with just an IPL. Here's one if you haven't run across one yet.

Here is a few things that might help you on your 140.

My sunday morning workout.
I thought it was difficult to level the rails on a strait bar with the new hand file tool!
Luckily it was pretty strait to begin with. Next to pic a 10-10 to try it out on.

Well I found the motor that was under all the grime, cute little thing

 

[edju1958]

Looks like you've got it cleaned up pretty good.When you open up the points box there'll be a small plastic disc in there on top of the points.It's important that it goes back in the same way or you'll have problems down the road.What does it have for a carb,Walbro MDC or Zama M1M7?

[Todd Loosli]

It has a MDC 13 , I saw the little plastic piece in the point box. The points are hardly opening at all. Sometimes I have to wonder why I'm messing with this saw then I go it's my very first McCulloch .

 

[edju1958]

I'm assuming you know how to set the points?They're fairly easy.I've only been doing tem for about a yr.now,when I first started doing points they used to scare the BeJesus out of me,but I'm over that now.Lol

[Todd Loosli]

Is that a walbro carb, I haven't set points on anything but a old Chevy with a dwell gage and Allen wrench. What do I have to do

 

[edju1958]

This is much easier than setting points on a vehicle.You must determine when the points are open.There's a screw that will loosen the points to move them.I put the nut back on the crank & turn it as if tigtening to see when the points open.Loosen the screw to open the points & set them to specs with a feeler gauge (not sure,but I think it's .018),your IPL should have the correct gap setting listed.What I like to do though is take the points right out to see how dirty or tarnished they are.If they're pitted,or burnt badly you might want to get a new set of points.They can be found on Ebay fairly reasonably priced.Not sure,but the part # for the points might be 88811.If te points aren't too bad they can usually be reused by cleaning them.I like to use fine grit (320) emery cloth.Sandpaper tends to leave grit behind,but can be used,but clean thoroughly after cleaning with both emery cloth & sandpaper.MAKE SURE YOU DON"T GET ANY OIL OR GREASE ON THE POINTS! I don't remember if there's a felt in the points box,if there is put only ONE DROP of light weight oil (20 weight) on the felt.I hope this was easily explained & understood.If you run into any problems let us know.

I picked up this PM700 on Ebay a couple of weeks ago for $45.I figured if nothing else I'd have a parts saw for my other PM700.It didn't have any spark when I got it.You could see ther p[revious owner had tried messing with the plug wire where it screwerd into the module,but wasn't very successful.I cut off about 3/16 in.off the end of the plug wire,screwed it back in to the module & had spark again.The fuel filter was the worst one I'd ever seen & I had to dig it out with a screwdriver.I put a new filter in & some fuel & primed the carb & it fired off.I couldn't get it to run on it's own or idle & I checked the needles.They were turned in almost all the way.I turned them out one full turn & stepped up the idle & it ran like a demon.It runs,idles,& cuts great!

You suck and have the pictures to prove it

 

[Todd Loosli]

Forgot to mention that is a nice saw and I'm a little on the envy side. How big is it
