Title: help finding carburetor
Post by: ratface on July 22, 2014, 09:32:58 am

Hi all, hoping someone can direct me to a source for this carburetor. I've spent several hours searching and can find every number except mine.  The saw is a Yard Machines model MS40 and of course any search into MS40 brings up Stihl. Shame on them for using this model number!  It seems that yard machines is really MTD but again that's no help. The carburetor is a "Walbro WT750". I can find similar Carbs on ebay and rebuild parts on the Walbro site but cannot find the actual carb? Anyone know where this rascal is hiding?

Here is a parts list for the carburetor as well as the size.

It says that it came on a McCulloch chainsaw

I think this little chainsaw was also sold as a Ryobi and as a Mac

Look at 40cc chainsaws in these brands

Thanks Karma. I kept finding that website but I just want to buy the entire Carburetor. Similar ones on ebay are going for 15-20 bucks. I'm willing to go that far on fixing the saw. I can't see where Walbro sells carbs, they just sell parts? The saw is definitely a yardmachines/MTD. It seems that pretty much every saw uses a Walbro Carb?

Walbro's prices for the carbs on their site are too high.

Many chainsaws have Zama carburetors.

One thing to keep in mind is that MTD themselves, do not make chainsaws. MTD merely markets Chinese chainsaws that are sold under other brands also.

Those saws are also sold as Homelites

Here's possibly some carbs for that type of Chinese made chainsaw. Compare pictures with what is on your chainsaw? The WT-750 is only 10mm which is a weed whacker size.

If you click on the walbro site the whole carb part # NLA.  WT-750-1    Carburetor    No longer available 

So you will have to find NOS or a good used one somewhere.  I will post link if I find something.   

Can you rebuild your old carb maybe?

I don't know much about rebuilding and it's a cheap saw. It's a backup saw for my Stihl. Didn't see it on that page, I've searched all of ebay. Thanks guys!

Put a carb kit in it and check your fuel lines etc IMO.  You might have $10 in it and your time.
