I do similar with my seal. I just do a small puncture with my thumbnail. Some saws are still a pain due to placement of the saws fill cap.I’ve been spilling that oil for years and finally got smart. On a new jug of oil instead of pulling off the seal off I just poke a hole in it about the size of a pencil. Makes it much more manageable. I also cut the bristles on a small paint brush, drill a hole in the handle and tie it to the handle of the oil jug… for cleaning around the saws oil filler cap.
McCulloch Chain Saws

I've become a fan of cans of compressed air for dirt around the caps.
Is there any way to adjust or reduce the "sensitivity" of this style chain brake on a 10-10? I have this saw all together but the chain brake engages with almost no pressure, and it will even snap just from the vibration of the engine at idle.
Or do they just get worn and become useless?
I do have another clutch cover / brake that I could use, it's just not nearly as nice as this one.

Perhaps just the latch could be replaced if worn?
I was wondering that too, OR could I possible re-shape the latch a little with a grinder to make it catch better?
I'll take a look at it later today.
Plan B at least for now. Old, dirty ugly clutch cover / brake, but it works!
Paint it black
I actually kinda like it haha.
You can carefully file the latch and make it more secure. I say carefully, because it is certainly possible to make it too positive and make the inertia operation of the brake ineffective.
Replacing the latch is also an option, but since you already have everything, why not try making small adjustments first?

I agree Mark, when I have some time I'm going to see if I can carefully file the latch to make it catch a little better.
In the meantime, that old yellow brake seems to work fine, it's just a little rough cosmetically, but it has character.
I have reshaped one succesfully. Takes a lot of time because as mentioned if you go too far then it will not let go when it should. I used a good file. Lots of take a bit then test, then go more and test. That latch is rather hard metal but a good file will do it. I bet i had that thing apart and together close to a dozen times. Became good at it after a short time.

A pain of a skill, well earned
I much prefer those clutch covers. Feel the weight difference.
Max and Alan brought me an interesting piece to add to the collection/display, McCulloch PM8200 Cut Off saw put together in Japan.
Alan also brought his Mac 91 saw, beautifully done...
...and his "White Lightening" Mac 92 hot saw.
Max also brought this G-70 done by Bobby Framke for us to look at.

Neat stuff Mark. Glad to see a new addition.
That 91 is a beaut!!!
Alan had a chance to give the 91 saw a bit of exercise.
We took the hot saws out for a bit of fun.

Is that a Mini Mac sitting on that log in the last picture?
That would be my contribution to a McCulloch saw competition haha.

He's got high apple pie In the sky hopes...
I love it haha, 12 inches at a time!
So at one point in my life the only saw I even owned was my Mini Mac 30 with a 12" bar, and I was grinding tree stumps as a side job. There were more than a few stumps that needed to be cut shorter and all I had was my Mini Mac. It took some effort and resourcefulness to shorten some rather large stumps with that little saw!
