    Hard Chrome vs. Nikasil Bores?

    Chrome & Nikasil Chrome plating is basically that; chrome is stuck to steel through chemical or electro- plating. The idea here is that the chrome has wonderful slickness and resistance to abrasion and makes a cylinder bore better through reduced friction of the ring rubbing against it. It's an...

    McCulloch SP81 Compression Question

    Sedan, I think we're both right, the schraeder valve is at the gaugehead part of the tester, not at the end of the hose that has to be used to connect to the sparkplug hole and then to the tester. The piston is having to pump up the pressure in the hose and in the cylinder before it ever gets...

    McCulloch SP81 Compression Question

    Hi Lewis, No, I never did retest the compression in the Mc Culloch, I did retest in the Husqvarna 42 and got only slightly higher compression numbers and this was after a pretty good run of the saw. I am going to lay the low numbers down to the type of gauge I was using which is a pro...

    Sachs Dolmar 166

    Certainly try the spark test with a different plug, with a spark tester, or with a gullible young 'un (Me and a buddy actually did this when we were teenagers and has a lawnmowing biz). I have seen plugs with some sort of internal short that makes you think something else is bad. Make sure your...

    Olympyk Bar Needed

    Wonder if anyone could point me in the right direction here. I have an old Olympyk 254 that I just bought and I need a bar for the saw. Here goes: Bartail pattern is what Oregon calls the D024 and this interchanges with some Jonesreds. This is not the same as what Oregon says fits this...

    McCulloch SP81 Compression Question

    Yeah, it is a vibrator. Loud as all hell too, but indeed powerful....I never could get the thing to turn over well w/o the compression release before, and I know that feeling well when you yank the rope w/o the compression release, sort of a painful tingling... Now....it's like a trim saw to...

    McCulloch SP81 Compression Question

    Parts for the SP81 OK, I don't have a problem with pulling the thing apart to take a look inside. I think I must have a broken ring or two as there is little scoring inside the bore that I could see (Steel bore, not chromed, this is an OLD saw). The question is where do I get the seals...

    Orline Chainsaws

    Yeah, the bar is just wide for a trim saw, the chain is bigger than most trim saws, mine has Oregon #12 chain and they're not that heavy. I would like to run it. Anyone have a set of points or a good source to get them from......

    Orline Chainsaws

    Orline 129 Mustang Need points and condensor I have one of these saws, I think I picked it up at a garage sale once, of course it didn't run. I tried to start it but had no spark. I took the thing apart a few years back, lost the points set (I still have everything else). I wonder if anyone...

    McCulloch SP81 Compression Question

    Hi All, I have an old SP81 that my father bought new in the 70's and that I use from time to time on larger live oak. The saw recently had a problem crop up in that it wouldn't stay running at idle and high speed power was down a lot, finally the saw quit and wouldn't re start. Spark was fine...
