Which Walbro carb? Super EZ

[treefarmer2]

Can someone tell me which carburetor I have on my Homelite Super EZ Automatic? It has the numbers 21-109 on the top of the carb.

I have the Service Manual. It says that it should be a Walbro HDC carburetor in the Super EZ. But it seems that there are different Walbro carburetors.

I bought the chainsaw from an estate sale. It’s in great condition, but hasn’t been run for 20 years, so I’m thinking I should clean all the old gas from it.

I want to buy a carb kit and want to make sure I get the right one. Are there additional numbers I should be looking at/for?

Thank you!

Welcome to HOH! ON the side of the carburetor near the adjustment screws, there should be a model number stamped like HDC-1, HDC-4, HDC-44, etc... However a Walbro K10-HDC kit will service the gaskets and needle in all of them.

I second that! Likewise, I would recommend only using a Walbro OEM kit; never had good luck with any of the cheaper aftermarket kits. Also pay close attention to the intake gasket, I generally like to make a new one once I've had the carburetor off. Sometimes the carburetor doesn't reseal great on that old original one. Good luck with your project. Love those Super EZ's.

Thank you for that good info. I've now bought an OEM kit and an intake gasket.

Does anyone know if there are any Take-Apart instructions for the Super EZ (Or any similar saws?)

I found the Shop Manual, but it doesn't have anything on how to take it apart.
I know it may be obvious for people who have done it before, but it's my first time.

It would make it a lot easier to only take apart the parts that need to come off and not have to spend so much time on trial and error.

I want to take out the carb, so I can clean it and put in a carb kit and I want to replace the fuel line and fuel filter.

Thank you!

I've had dozens of these apart; actually not that complicated (I know, easy for me to say), how far do you want to go? Is the compression good? Or do you need new rings, piston, cylinder? Do you have a points saw and no spark? You'll need to remove flywheel to get at those parts. Removal is easy with a puller, not a big fan of the hammer method, but it works. Fuel line can be down without a tear down, new oil line is easier with the tank off but that requires flywheel removal. Clutch removal requires a "special tool" but can be easily made from a piece of flat stock. The oil pump which is under the clutch easily comes out and can be cleaned and reinstalled. Starter rope and rewind spring are accessed from the outside cover (on the pre '81 models with metal side cover). I think I've covered most major components, what do you need help with specifically?
