028 AV oil leak issue.

R

RANCHER

A friend gave me an old 1970's vintage Stihl 028AV with electronic quickstop. I cleaned it up and it starts, but it's got some carb issues. The idle adjustment screw doesn't work right. It doesn't really adjust the idle and it looks like the wrong screw to me. It doesn't have a spring on it, like it shows in the user manual.

But, the major issue I'm having with it is that it leaks bar oil pretty badly out the bottom of the saw. What should I check and how?

Does anyone have a shop manual for this saw they can lay on me?
 
There is a forum on treebuzz that is chainsaw specific.

You might take a look at the beg for manuals thread on arborist site. It is a great resource. Just make a post asking for what you need.

Check the oil lines/system. Likely you'll have to tear it apart pretty good. I'm not familiar with that saw though.
 
The oil tank on a chain saw is created by two voids located in the castings of the crank case. In between the two halves of the crank case lays a gasket that forms the air tight seal for the crank case and oil reservoir. Most likely that is where the leak is coming from and would likely be not cost effect to properly fix. You could try and use some JB weld or similar product to stop the leak though.

If you go the jb weld route, you most clean it perfectly. I was quite careful know welding an oil cap that was cracked. I wasn't careful enough and other leaked.. oil is sneaky.

The best epoxy for fuel tank repair is not JB Weld, it's an epoxy called Marine Tex.

Looks like good stuff. Thanks for the tip. Do you usually just order it?
 
Is there a West Marine outlet near you?

If not just order it online.

The only epoxy I know for a fact will seal a fuel tank on a chainsaw.

Clean the parts extremely well with ether starting fluid, let dry, and seal her up mate!

Works on murder sickle tanks too!
