Check the latex hose up through the hole missing the welch plug in the cylinView attachment 126607 der

Looks like the same location
I guess the welch plug guy or gal was asleep a couple of times.

Ya, it’s kind of funny, the same one! That why I had to post a pic! Lol

If they had named those ''Scottish" plugs, they'd stay put.

Haha, Drum roll please! Lol

Tim I had a CP with the same problem. When I got it, It just would
not want to run so I shelfed it. A few years later I came across it and
found the plug missing. That saw got a total resto.

Aye, but they fight you every step of the way putting them in.

I guess it was more common than I thought. Was it the same plug closest to the muffler?

Is a sealer used on top of those plugs after they go in? I think I've seen some with some orange / red stuff on them before.

 

[Bigmac]

I wonder if they had problems and switched Sealant, my CP cylinder has original paint, and has more of a gray sealant, and my other cylinders that I have no paint a red seal sealant, my CP cylinder has original paint, and has more of a gray sealant, and my other cylinders that have no paint and red sealant, along with 101 cylinders. I wonder if heat was a problem with the sealant on the exhaust side Welch plug.

 

[fossil]

Sure could be. I'll bet there was a bulletin on that. I heard MAC was big on issuing those but I don't have access to that stuff.

 

[Lee H]

Those plugs are a welch type plug. When installed they just fit in the hole. Then you flatten
them with a suitable flat punch near the same size so they expand and grab the hole they are in.
The sealer is kinda an insurance in case they didn't seal just right.

put the 10-10s too work today went like a dream

 

[Lee H]

Those 10-10's can be pretty impressive. Worked on a ton of those along with
the Homelite XL12's and Super XL's back in the day.

I found today after my 125 sat for a few months that I'm getting bar oil in my crankcase. What would be my first course of action?

 

[Bigmac]

I would pull the oil tank and stuffer, check for corrosion on the stuffer or bad gaskets

 

[heimannm]

The automatic oil pump operated off a crankcase impulse signal. Very possible there is a gasket leaking a little.

Thank you guys.

I agree, but the auto Oiler gasket shouldn’t be a problem unless it’s running, a cold start oil leak is stuffer? Right? Unless it is filled to the max and leaks through the port
