Just had a idea that might be happening. The black oem fuel line might be collapsing.  I had to put on a new filter and noticed the fuel line seemed very giving.
It will start run then die. I was thinking coil or carb kit. Coil checks out on tester.  Then I thought maybe fuel line collapsing.

Anyone seen this?

So nobody has seen or heard of a fuel line collapsing in the tank? 

I'm going to undo fuel line and run a redneck 2nd fuel line and filter to a can and test my theory of what may be happening.

I think I've seen two of these things in my life time.One a neighbor next to my shop has and one in a dealers dead pile .
That surprises me. They were very popular here with farmers and firewood cutters.

There are a lot of 031's & a few 032's in the North Central Ohio area. You see them on Craig's list all the time and there's usually a used one in the chainsaw shops

Friend of mine bought one new in 1979. I service that dang thing for him and sharpen about 12 chains at a time when it comes in.

Just figured it out. Always showed good spark when tested with my new spark analyzer tool and old school tester. 

So I pulled carb put in new kit. new fuel filter etc.  Start and runs a few mins and then boom off.

So I put on my old school spark tester after supper.  Got it started and watched the spark. Seemed good then once it warmed up boom no spark. The typical 031 spark BS. Oh well.

This one has the old school stihl emblem on it. So guessing it might be a points one?


Like this one.

I think you are correct on points. Are you going to convert it to electronic ?

Nope I dont do that as this is the 2nd one I have had come in needing the atom. IMO the saws aint worth the time and money. JMO
One of those deals I choose not to work on.

 To me these are 50-100 saws.  Unless like new then maybe 100-120 like the one I sold for Jim

Now if owner of said saw was to do it for themselves yeah all for it.   ;)
