MCCULLOCH The official McCulloch thread

[edju1958]

I've been MIA for the past 3 1/2 weeks due to another back surgery that didn't go quite as planned.I ended up with a compressed sciatic nerve which prevents me from sitting more than 5-10 min.I am on the mend though albeit slow.
Currently I'm back to working on my PM55.I've run into an issue with the points - therer's no cam wiper in either one of the 55s I have.I looked on Feebay,but at $6 for one felt I think that to be ridiculous.One would think that the cam wiper/felt would be included with the points,but I've not run into that.Would anyone here have a couple extras they'd be willing to part with?

For the felt, would a slice from a chalkboard eraser work? Something like this? https://www.officedepot.com/a/products/795322/Sparco-All-Felt-Chalk-Board-Eraser/

I would say no because it would seriously hinder airflow. If one had to,pleated furnace filter media would do. Of course the compound curves on the dome filter would prove challenging. Before I found a good filter I used a velocity stack and come filter from a pocket bike. You couldn't use the stock filter cover but it looked cool!

Steve this idea was felt for points cam wiper , not as an air filter

I know I've probably got 2 Ed , if I lost your adress I'll PM you. Should be just a stamp.

As you can see all the frocking was missing from the filter screen, I sowed the uni filter over it with fishing line. After a year being pinned down by the cover I think it would stay put on its own now.

I got some time in with the PM55 today after my dr.visit.I don't think I've ever had such a hard time trying to get spark on a 10 series saw.I had a 10-10A that I checked spark on the other day & pulled that coil off.It had nice blue spark.I put a different coil on the 10-10A that was testing dead on my multi-meter & it had good spark & the saw ran on a prime.Fast fwd.to the 55 today.I put that 10-10A coil on the 55 along with 3 different condensers & a chip & had no spark.I'd cleaned & gapped the points yesterday,so I knew they were good to go.I ended up putting a brand new coil on that I bought from Bob J.last yr.The chip was still connected & it had no spark.Just for the helluvit I disconnected the chip & plugged the points wire back onto the coil & I had good blue spark.Now,what are the chances of having a coil go bad by removing it from a saw & also having a bad brand new chip at the same time?

Is the plug wire replaceable on the Mac 7-55 ? It look CRISPY.

I haven't replaced the spark plug wire on a two man coil yet but it has a separate part number so it was intended to be replaceable. The wire basically unscrews from the terminal, but if it was secured with a good adhesive it may twist the wire off. I have been able to remove the broken off wire with a hollow, left hand drill "bit" that is intended to be used on broken wood screws. If you have to go that route proceed a little bit at a time and frequently clean out the material that accumulates in the bit.

My cheap-ness would suggest the filter media from a cigarette butt.
Can pick one up for free from any local tavern parking lot.

What you might try is HEPA filter media used for vacuum cleaners .I used this stuff in layers for making face masks during the lock down a couple of years ago .The large filter bags used for commercial cleaners are relatively inexpensive on flea bay .

Thank you so much

Thinking outside the box you could use micro filtration stainless steel mesh and filter media sandwiched to DIY make the flat filters for McCulloch filters .I did this only once to repair the clip on filters used on early Partner P-100 saws .Those were later replaced by the more modern type similar to what Stihl uses .Took me a year to find them for a decent price .Like I've said restoration is not for the impatient .

Not a bad idea Brent.And I can get them pre-flattened to fit after they've been walked on a few times.And to think of all those butts I threw out when I smoked yrs.ago,Lol.

Nice score! Why the black starter cover? Does it have it's tag in the airbox?
