McCulloch Chain Saws

[Nickolas]

Some McCandy for you folks.

Like new 3-10E and PM 850 Super. I decided to fuel them up and see if they would run yesterday since they've both been taken to the woods in the past. I have mixed feelings about the PM850S, it actually started on the very first pull. A saw like that could ruin the McCulloch reputation.


I have several McCulloch saws that start on one or two pulls. I think the hard start issue myself is lack of maintenance and care. These saws are 30,40,50 years old and need attn. I pretty much rebuild every saw with at least gaskets and seals and have very few problems. I have a few that start with one pull every time and some three pulls, two choked and the third is running. The primer saws are the ones that start the best and manual choke next. I've always been one to do preventive maintenance and it makes a difference. I don't wait until i have a problem i prevent them before they happen. I rarely have starting issues with any McCulloch saw they are very reliable saws regardless of what people say about them.

dang. if i'd only waited another day. sadly I already bought one off the bay. nice offer anyways.

while cleaning up the muffler for my 10-10A last night I discovered it has a short life expectancy. has some corrosion (rust?) damage. anyone got one they'd part with. got stuff and $. there're some on the bay but thinking i'd give it a shot here first.
also, without looking REAL close it appears that the two holes comprising the exhaust port are different sizes. is that so or do I need to start chipping?
thanks, jerry

Kind of happy tonight. I was able to get my late FIL's 1-42 going tonight. Put a carb kit in and it seems to run pretty decent and oils good also. I just need to tune it a little bit. I know it is not a speed demon but I just wanted to get it running right. My FIL left me two complete 1-42's and I got the better looking of the two going ( the other one is really rough but it will be nice to have a parts if I need them). It will be more of a conversation piece than anything else but I will enjoy making a few chips with it every now and then.

anyone got a clutch cover for a 10-10A, model 600002U? As you can see, this one has been a victim of white death. I believe it was set down when the compression went south. other than this (I was able to fix the starter) I believe it will be good with seals and rings.
also, anyone got a template for the spikes?

Anyone point me in the direction of a 30" or longer bar to fit a Pro Mac 800? This saw will need various small parts as well. Anybody with a parts saw get in touch. PM or reply here. Thanks

Just finished this one up a few days ago. It was missing a muffler, and the bar stud had to be replaced, but everything else is fully functional. I've been using it in the woodpile this week and it's quickly becoming one of my favorite.

Power Mac 330.. Can anyone shed a little light on the oiling system for me? Can't get one here to oil whatsoever. Lever does nothing.
Thanks,
Jason

I would check the filter on the oil hose in the tank first.

There's good IPL on this site. PM330, they are about 3/4 down the page.
Page 17 has a good illustration of the pump assembly.

 

[heimannm]

Automatic oil pump is pulse operated off crankcase pressure/vacuum and is mounted right on the front of the saw with just a spring clip. Try taking the pump off and working the "piston" manually to insure it is free to move.

Finally got the updated spring clip for the Oiler on the SP 81. No more burning bar oil but the fuel line is leaking where it passes thru from the fuel tank to the carb bay.

Has anyone ever tried to add a barbed fitting into the fuel line passage using something like this?


or this?

 

[joeymt33]

I wrap the fuel line with Teflon tape and put it back in and that has stopped the leaks for me.

I'll try that.

I'll give it a try.

 

[heimannm]

Teflon tape is the easy solution.

I have done something similar to your proposed repair using plastic (nylon?) bits from McMaster Carr.



It is hard to change the fuel line in the tank later on if need be unless you are willing to split the tank again.

Looking at that cork gasket in the tank reminds me that over on SH in the McCulloch thread someone found some 3/32" square profile o-ring material you can buy from McMaster Carr, add a dab of Three Bond or Honda Bond at the joint and you have a successful gasket replacement.

Thanks Heimannm..... That's what I was thinking. Seems to be more of a permanent solution and doesn't limit one to purchasing the McCulloch specific line.

There have been a few of those piston/pin tool kit come up lately. They are handy when you are working on the small saws as it takes some special tools to press the pin out with the blind bearing in the piston. You can't use a puller like the bigger kart engines, the only way is to punch the center cover out of the bearing.

I did buy some of the small bearings (Torrington M551) a short while back, made a deal with a vendor for 10 pieces and I think they ended up sending me 30...
