My first attempt to fix an old 10-10 was a bad coil wire.IMO it was a bad idea to run the coil wire over & through the cylinder fins.It drove me nuts for about 3 months.The previous owner had put a chip in it on account of the condenser being bad.I got spark back on the saw with a different condenser & cleaned the points,but the spark was intermittent & I could hear the spark snapping.Laying in bed one night it hit me like a ton of bricks what was going on.I re-routed the coil wire on the outside of the saw & all was good.I was elated.I've had a couple more after that that did the same.I was able to save the wire with liquid tape - good stuff.

Looks like a 1-60
Agreed, 1-60. Looks tough!!
Huskadolmar, read back a page or 2 and see what i did. Tore down a 125 looking for an air leak only to realize i was running out of fuel. Lol
We all do silly things at times. Great thing is you figured it out.
I have a question for you. A guy gave me a dolmar 112 to get running. Its got low compression. Someone also held the piston in place to remove the clutch or flywheel nut at some point with a screwdriver and messed up the piston a bit. I want to replace piston with a new one. I found one for a 114. Will it work? Its a 2 ring vs the 112 which is a 1 ring piston. I asked on the dolmar forum but have yet to get a response. Just curious before i order one from across the globe.

1 ring vs 2 ring is no problem...i have a 112 silverstar and a 115 but no 114 so i dont have a 114 piston to compare the pin height and skirt shape to. I do know that a 112 is very port job and timing friendly so i am sure it can work. But i cant tell you 100% if it will drop in without work.

That being said they are same stroke and bore and will absolutely run with each others piston...just not 100 on the skirt being close enough to run the same

You will have no issue with it except a possible timing change

Now back to mac......i was watching billy ray earlier with a mac 200 and it inspired me to run my 1-43 through some red oak. Not exactly a speed demon but it is always nice to run the beast once in a while....i run a 28" hardnose mac bar on it and it loves it. Such a great sound too.
she is the beast to the far left

Thankyou. Appreciate the info.

Any time....glad i could help
It seems to me someone was asking about the McCulloch 170 welder leads a few pages back. I finally remembered to take some photos.
First up, the receptacles on the welder:
Notice the air/vacuum connections adjacent to the other receptacle.
One of the plugs, notice the two air/vacuum lines tucked in behind the plug. There is a thumb operated valve on the electrode holder to allow remote control of the throttle while operating the welder.
The other plug.
That little "canister" looking device next to the carburetor is a cylinder connected to the air/vacuum lines that are in turn connected to the crankcase. I expect there must be a duckbill or check valve in the circuit somewhere but I haven't torn in to one enough to know exactly how they work.

Very cool
Has anyone done cart motor modifications to a saw before?
Like open the third port?
Like open the third port?
I have run my SP125 along side a 795 that had been worked over by someone who knew what he was doing...my 125 could not keep up and that was with a 123 to 103 cc advantage. In this case the third port in the 795 was closed off with JB Weld or something similar. As I recall, reducing the volume in the intake tract leads to a much higher velocity in the transfer operation.

I watched a video on a kart motor modifications and wondered if it would work for the saws? I'll have to study it some more.
It likely will but remember the kart motors weren't made for longevity. I think they ran at around 13000 rpm stock and I read some guys modified them to run at 18000.

NorthEast Tennessee Saturday MAC Report
Another beautiful day in North East Tennessee today. Brian was off so the only MAC action was my felling of a Black Walnut and an Ash with the PM800.
Walnut went easy.
The Ash was leaning and limb weighted to the creek. Wedges weren't enough; it took a few tugs with the pickup to keep it out of the creek. Still twisted a good 40* from the face and hinge. Hope someone gets a lot of heat out of it - I invested a nice $12 wedge in it.
Brian should be along later in the week to buck these two.
Happy New Year!

Enjoy the weather while you can, I suspect some rain is coming soon. We went from 58 degrees and sunny on Christmas day to 34 degrees and rain today with heavy rain predicted shortly.
Finally I can spend a day inside and not feel like I am missing a great opportunity outside.
