tools needed to tune earthquake chainsaw

[farmerdoug]

I went to turn the "H" screw back out and realized that I need a special tool to do this. I have 2 earthquake saws and both are the same. What tool do you use?


P.s. Saw starts fine, but will bog down when you hit the throttle. Both saws act the same. I was told that the H screw is turned in too far and needs to come out a little.

Thank you for any insight you may have on this.

A hammer?

Probably some special type of screw. You could probably just open it up to get to the screws and cut a straight slot across the screws with a thin dremmel disc.

And if it bogs down when you hit throttle you probably have problems on the L side, but you should do a complete anyways.

single D or double D carb adjustment tool

Could it be a single d tool?View attachment 271983

IT takes a double DD driver.

IT takes a double DD driver.

Are you sure? Maybe ours are different. Mine is the single D screw.

Check out the "Dissecting the Earthquake chainsaw" thread on here. Will tell you how to adjust them.

I have never heard of a double D driver... but I like the sound of it

take the carb off,, take a dremel with a thin cut metal cutting disk and notch the end of it,, you don't even need to take the 2 needles out,, you will cut the carb housing but it won't hurt it

Some have slotted screws, some splined, some D and some double D. If you don't have the exact tool you can do a couple of different things.

1- Use needle nose pliers to get each screw out, slot it with a Dremel cutting wheel, re-install to have a slotted screw.

2- Use a piece of automotive brake line (steel) and push it over the tip of one jaw on a pair of needle nose pliers, then form it to the shape of the pliers. This will create a "D" profile. It may take more than one attempt to get the right size of brake line.

3- Buy the double D tool and be able to adjust only double D screws.

4- Buy the single D tool and be able to adjust both single and double D screws. (My preferred option.)

5- If all else fails, you can use a cutting wheel on a Dremel to cut a slot in the screw while it is still in place. You will also cut the carburetor body, but it won't hurt anything.

Double D's:msp_thumbup:

Someone in the thread suggested several times to make one from a piece of car brake line just smack one side with a hammer and then stuff it on. you can bend the other end for a handle.

Not sure about the Earthquack saws but I recently bought a spline, double D and singe D tool from a local dealer. Sure makes life easier having the right tool.

Nahh, still seems legit...

Easiest way to make the tool is to take a piece of steel brake line and thin it a bit on a bench grinder, insert one leg of a pair of needle nose pliers in the thinned portion and squeeze it to shape in a vise, the steel will form to the "D" shape of the plier point and your tool is done.

What size break line are you using to make it out of.

 

[singinwoodwackr]

An awful lot of posts about 'double Ds' but no pics...WTF?

Oh...wrong thread...

That's what I do :msp_smile:


But it sure does bring down the price of a $35 saw to about $33 :jester:
