McCulloch Chain Saws

[rwoods]

Nothing wrong with having more than one 82cc MAC so long as you enjoy using or looking at them or both. Ron

 

[Warped5]

Yeah, but Ted said I'm officially a hoarder now. A true hoarder doesn't make room. Let's see if Ted will agree to remove hoarder status as a reward if I get rid of one.

(Couldn't sit on the 'outside' any longer) Joey, your definition is true. However, you are putting up that new shop building at the new home site.

 

[joeymt33]

I will be milling with two of them. Using the others in rotation clearing the lots.

 

[joeymt33]

Ron, I need to get you a earlier 82cc saw that doesn't have the Q-port. I'm working on one right now. I'll keep you posted.

 

[rwoods]

Joey, I have had several but decided to go with the 800 for my needs. I even sold my NOS cylinder for $20. Too bad now as I am on the lookout for a primo 850 for a special gift to someone. Ron

Here a pic. of a disassembled 10 series oilpump.As you can see the valve spring is damaged.this doest oil properly.

Charles - the 10 Series fuel tank gaskets are getting hard to find at a reasonable price. I think someone was selling them on e-bay for $35 each but I decided to pass on those.

I didn't see any on there, but at that price, I can sit at the kitchen table cranking them out and selling them myself.

 

[heimannm]

Great find Joey. I have to admit the Titan 70 is intriguing...

I used the starter/charger yesterday to get my garden tractor snow blower running yesterday. I will be looking for a new belt this week.

So I'm becoming new to these older yeller saws. I'm working on that 55 Super. I made a fuel tank gasket for it yesterday. What a pain. Any how, how does the choke work? When I apply the button on the handle the choke lever closes but it doesn't stay closed. Am I missing something? Oh yeah, what size O ring will fit the fuel cap?

I know you can’t nominate yourself, so please someone nominate me for the NINCOMPOOP of the Year Award.

I also know it is presumptuous for me to outline my mistakes and post pictures to prevent someone else from repeating my mistakes as most know better than me. Nevertheless the PM800 seizure autopsy results are in. The seizure appears to have been the result of two screw-ups on my part. First, I didn’t sufficiently remove the old aluminum transfer. (Note to self: put bright shop lights on the Christmas list) Second, moisture built up in the crankcase from my repeated submerged leak testing resulting in excessive moisture and surface rust after the project sat untouched for several months – fogging with WD40 wasn’t good enough. The cylinder transfers and the case were filthy with a sludge containing fine rust particles from the crank and flywheel side bearing.

Even without my errors, the saw was a ticking time bomb as the new clutch side seal just slid right off upon removal of the bearing insert.

I believe the piston and cylinder can be cleaned. With new bearings and seals, I’ll try again but no more submersion in water.

The oiler demise: same thing – moisture caused the piston to stick.

BTW there is a metal liner in the plastic housing just as Fechtichmac pointed out in his post. (Reminder to self: add upgraded shop lights to Christmas list)

For inquiring minds - yes, that is a table saw being used as a work bench.

Scott - Find a big log, lay the saw over the log and hold the throttle open and choke closed with your left hand, pull the starter with your right hand. There is no throttle lock or choke latch on that model.

Ron - Ouch. I have 9 units of 8' twin tube HO fluorescent lamps in my 24x36' shop, and the walls and ceiling painted white, that helps a lot. There are still some areas where addition task lighting is beneficial. I will be looking for some alternative lighting suggestions for Jeff's garage as it is unheated and the fluorescent lamps just don't work so well in the Iowa cold.

My own nincompoopery for the weekend involved trying to rebuild a 10 Series fuel tank cap with cold fingers. I don't expect I will ever find the original spring...

Yeah that's what I thought. This should be fun because I'm left handed and need to pull the rope with left hand.

 

[heimannm]

No problem Scott, just find someone right handed to run the controls while you supply the motive force for starting the saw. You can call it a two man one man saw...

[awol]

Like Mr. Heimannm said, you can lay the saw over a log, hold the throttle open and choke closed with the left hand, and pull the rope with your right hand. If the bar is short enough you can rip start start it also.

I did some sawing last week with old Macs, 797 895 795 125x2 380 DE80

 

[sefh3]

It does have the flywheel on the left side and one on the right. Did they make this an ambidextrous saw?

 

[Eccentric]

There were no carburetor "kits" for the 3-25 saws. You can find some of the gaskets and diaphragms, but you will likely end up having to make one or two as well.

I do have a few of the diaphragms with the hook on each side if your 3-25 is one of the older ones, I probably have a few other gaskets as well. Look over your IPL and send me a PM with the items you are looking for.

And while we are on the subject, do any of these parts look interesting to you Eccentric? The part numbers for the diaphragm with the hook do not agree with the 4-30 / 47 part number in my IPL's but I am wondering if they will in fact fit. I am not sure where the one with the plate is supposed to be used.

That grip will be perfect for my S-250. I'll have to pull apart that 4-30A again to refresh my memory re what type of diaphragm it needs. The IPL does show the hooked diaphragm (#19619..................I put the wrong # in my last 'conversation' message).

I liked the Pro Mac 700 I picked up a week ago alot, so I picked this critter up tonight. P&C look great, huge compression. Not pretty and the muffler is rusted out but I'm looking forward to getting this one going. Two shoe clutch and roller starter.

 

[joeymt33]

Nice saw! Mufflers are hard to find. That saw has the cold weather filter cover.

I guess I'll have to braze some steel on the muffler.

 

[joeymt33]

You can use a sp80, sp81, sp81E, or pm850 muffler. One may turn up one day.
