McCulloch Chain Saws

[promac850]

Nice 1-43!! That should be a fun saw.

A man came by the shop today with two saws that he thought I might be interested in and I bought both of them. One is a Mcculoch 890, price $45.00 It has weak fire and weak (90 #s) compressio. Everthing else looks good, except the airfilter. and it will possible clean-up in the ultrasonic cleaner. I know I am going to catch ++++ for it, but the other one is a Stihl 048 Super, $100.00. It has good fire and 165 #s of compression. Looking at it I see new sprocket, new carb kit and new airfilter. I would appreciate it if someone would open the pictures. Two question: I can use my McCulloch 790 IPL for the 890 on such items as rings, piston and seals? The second question is: the McCulloch has a Mac carb. I have a Tillotson 63 carb. How much trouble is it to change. Thabks for any help. TomView attachment 191339View attachment 191340View attachment 191341View attachment 191342

You can make the HL63 work, but an HL19 would be more of a direct fit. Not a big deal. You'll have to remove the air filter stud from the HL63 to use that carb on your 890. Don't cut the stud, but instead replace it with a bolt. Somebody may want/need that stud........I know I could use it. That stud is for the front-tank Macs (250, etc) and holds the AF cover down. On the top-tank Macs (like your 890), the carb body isn't drilled/tapped for that stud (since these saws use a sheet metal bracket with a capured nut for the AF cover stud). Your 890 will also have a governor, and the stock carb has a weird throttle arm that's just pulled back by the throttle link (against spring tension). The rod doesn't securely connect to arm with a 'Z' bend (like an HL63 on a front-tank Mac). The other side of an HL19 has the funky roller-equipped arm that mates with the governor linkage. If you want to retain the governor you'll need to use an HL19 instead. Alternatively, you can use a throttle link with a 'Z' bend in it on the HL63 and do away with the governor if you wish. I put an HL63 arm (well actually an arm from a Homelite HL) on the HL19 in my 790 to eliminate the governor.

3/32 stainless tig wire.

How do you make nice clean/sharp little 'Z' bends in the wire Lee? I need to make a replacement choke link for my 650 gear drive (which had a primer flatback). The link I took off of a parts saw (choke equipped) was a hack homemade replacement.

I am going to see if I can find a bolt for mine tomorrow, if I can I will happy to send that piece your way.

A little heat with a small tip on my torch set.

They make a Z bender for small gas engines, it should work for a while bending TIG wire.

Thank you sir. I could use one for my 1130G. Should be 1/4-20 if I remember correctly.

One more reason why I need to pick up an oxy/ace setup. Thanks Lee.

I've seen 'Z' bend tools and pliers for model airplane control linkages. May pick one up. Gotta see what gauge wire they can handle.

I think this will do for bending wire : LINK


But I'll never discourage someone from getting a new tool.

Very interesting day guys, thank to Tom, Lee, Aaron, and Vic for giving us all a little insight and inspiration.

You too PM for helping out with the photo's.

Not much to report this week as I'm busy in a plant all day long and not really in an area with any saw shops to look at.

I was sure my first 6 cube saw was going to be yellow but it appears it is going to be red and green. I feel like I'm cheating.

You are forgiven my son, go forth and sin some more.

No pictures, did not/has not happened.

Everyone knows Santa loves red and green.

Rats!!!

Took a closer look at my 790 last night after our earlier 890 carb swap discussion. Saw that what I had thought was a sheet metal model/serial # tag on a carb bolt was something else. Somebody in the past broke part of one of the carb mounting ears off of the intake manifold/tank body and used a piece of sheet metal to give the bolt head something to pull against. I had wondered why the 'tag' was on the wrong side of the maniold ear (they're usually on the nut side instead of the bolt head side), and why it had been bent over the top of said manifold ear. The ear was in fact gone. I'm surprised the dang thing runs without an air leak. Looks like I'm in the market for a 700/800-series fuel tank in addition to the oil tank and crankcase stuffer I need for RandyMac's 790...:bang:

Now that is a pisser.

I know what the feeling of being so close to done, and something else goes wrong... it can be quite infuriating...

What I've done before is grab the .22, head out back, set a target up and shoot the #### out of it. It works. :msp_smile: That's one of the perks of living out in the country... get your guns out and shoot just about whenever you want to.

Used to be able to do that. Too many close neighbors now. Maybe I'll get out to my buddy's ranch this weekend.

lol. Screw the close neighbors... :jester:

If they don't like it, they can move...

The neighbors on one side of our property tends to ##### about us shooting skeet, and especially stuff like the .308... (he's one of those guys that feels unappreciated, probably a side effect from working at GM... everything he owns is spotless. He washes and waxes his JD 430 just about every other mowing... you understand the kind of slightly weird and self-centered personality is what I'm talking about...)

Ah, if they I(he, mainly...) really can't stand it, they can move...

Is it that you don't have about 500 yard sight line straight back off of your property where neighbors are about a mile and a half away, behind a backstop? Or are you in the suburbs...

Suburbs kinda suck, but definitely are much better than the city, especially the inner city...

Aaron, I have a 797 tank and some of the other remains, it should work.
If the Redwood Empire GTG comes off, I'll bring about 50 pounds of stuff or
maybe send it sooner.
I got lots of other "things" brewing, haven't done anything constructive in weeks.

Yes sir and so it is that I have!

I edge ever closer to returning to bench-top kart-motor machinations. Along the way, I have been crossing things off the to do list. One such item was checked off yesterday when I was reunited with the pictured 1206 for a smokey pass across dirt owned by a major state University. Amazing that such a bastion of little evironmental nazis would tolerate sun-blotting haze due to injudicious pump settings... Gloriously entertaining.

Great pic of the 1206 cpr - looks awesome. 'Injudicious pump settings' - I was tied up with Cummins years ago, and quite often owners had to give up warranty due to their fuel pump settings. When you came across a pump without its security wires and lead seals you knew what may be around the corner. Great fun though running some of those beasts - enjoyed watching startup when a great cloud of black smoke roared its way out of the exhausts!

Thanks for the photo,

Chris.
