Title: Eager Beaver won't start
Post by: Sodie on March 21, 2016, 02:26:05 am
I just got a slightly used Eager Beaver Mac 100 series chainsaw and it won't start. I opened a few of the covered areas to see if anything was wrong. Cleaned the air filter and I pulled off the fuel tank to see if any liquid was coming out. I think that the fuel filter is completely plugged up. Fuel should leak out of the filter area when detached, right?

Is this something that I can fix? New filter? 
 
Ignition/Spark seems to be good as I can get it to turn over for a few seconds with a shot of ether.

I tried calling around but no one nearby me works on McCulloch chainsaws.

You might find a weed wacker fuel filter at a lawn and garden store or a big box store like Home Depot? This filter should work for you.

The fuel filter is inside the tank and you will have to fish it out with a bent wire. It just plugs onto the fuel line

A older saw like that has rotten fuel lines too.

It took a while but I found a replacement filter on ebay. I got most of my cutting done but my chainsaw doesn't idle well, especially when it gets hot. It likes to stop if I take my finger off the trigger more than 10 seconds.

Does anyone know how to adjust the idle on an Eager beaver? There are three screws, Idle - lo and high.

Thanks

My Eager Beaver also would not start after sitting idle for a couple of years.  However, when I removed the top cover and the air deflector, I had access to the open top.  I sprayed in a little carb cleaner because my starting fluid can was empty.  (Do not use Gumout cleaner.) With the choke closed and the throttle lock pushed down, after 4-5 pulls it started and raced to high RPMs, only to stall out after 5 seconds of smoky exhaust.  At least now I knew the spark was working and timing OK.  I tried pushing the primer button, but it seemed hard and I could see no bubbles in the gas tube.  I took off the line closest tot he primer button and blew into the line with my mouth...seemed plugged.  I emptied all the gas out and removed the gas line furthest from the primer.  When I sucked on that, there was resistance, but suddenly a little gas came into my mouth.  I  noticed that this gas line would pull out of the gas tank and suspend the  filter inside the tank so it was visible.  Cutting a fresh end on both gas lines, I installed them on the carburetor.  This makes it necessary to remove the two screws holding the carburetor to the engine.  This makes it necessary to put a little non-hardening gasket sealler on the gasket beneath the carburetor as well to make sure there are no leaks below the carburetor.  Watching the gas lines again, I could see gas flowing in the gas lines.  I then tried restarting the chainsaw and....vole la... it started and kept running.  I reset the two jets at 1 1/2 turns from seating, replaced the foam air filter using a piece of 1" thick poly foam that had been packaging material    (This has to allow air to pass through, so if you don't have any such foam around, you may have to buy a new filter which could be hard considering the age of the saw.)  Buttoned h her up and am again able to use this great little beast.
