I have been tinkering with this cool lil saw.
These saws were made by Remington (Mitee-Mite),
and rebadged by Monkey Ward.

I was able to source a carb kit and surprisingly this thing starts right up and runs strong.

Here's the problem, When I fill the bar oil tank, she starts up and runs strong...
...and SMOKES like crazy..

I took the oil pump cover off, and I found that the crank case vents into the oil tank.
I searched the inner tube and read somewhere that the oil tank must be able to hold a certain amount of vacuum,..
or was it pressure... I dont know..
The gasket for the oil pump housing is in sad shape.
I caint seem to find a new gasket anywhere.

Do youse guys think a new gasket would solve my problem?

I think I can save this one with a lil RTV.
My main question is..
Why would they locate the crankcase breather in the oil tank

IIRC, the auto oiler works off crankcase pressure for oil exit at the bar. Oil tank must hold some pressure. There should a check valve to keep pressure from flowing back into crankcase - if not, lotsa smoke cuz you may effectively be at 8:1 or 16:1.

This is what I was suspecting.
The breather fitting is actually a check valve?

Anyhow, awhile back, I found that the breather fitting was 1/8 pipe thread.

I replaced it with a brass pipe plug, I figgered that would keep the oil out,
and it did, but I am afraid to run it like that..


My next question:
if I plug the hole between the oil tank and the crankcase,
will the engine want to Vent somewhere else?
Will it blow a the head gasket or push past the crank seals?

You gotta have oil getting to the bar. If this is an Auto Olier ONLY - gotta be from crankcase pressure. Some old Macs had both auto and manual oiling - if auto quit, you just pushed button occasionally. I don't know your model but bet that should be a one way valve.
Most saws (and other small 2 cycles) don't have a crankcase breather - there's no head or valves. They do have a tube or port to the carb for fuel pump diaphragm to flutter.

This saw has a thumb operated manual oil pump
Also every time the the trigger is pulled it activates the oil pump..

I put the plug back in and buttoned her up.
I wonder where a guy could find a new clutch/chain/bar?
Maybe I can find a new check valve... I dunno...


I will go search the innertube...

Thanks again fellers.

I took the ol girl outside to see if she would start,
she started right up and the clutch and all related pieces and parts went flying everywhere...
I had been tinkering with the clutch. I had all the pieces in the right spot...
I forgot to tighten the clutch with my new 'custom made just for this saw' tool

If nothing else I have a cool lil wallhanger that runs..

Unless the bar/chain is installed, the clutch will unscrew during deceleration after high rev, then go flying. I've shot them down the driveway, across the road, into the ditch.
