My 064 has the dreaded Bing 49 carb. It's in need of a rebuild but rebuild kits are very hard to come by. Does anyone have a recommendation for a carb swap that is still being supported? My dealer mentioned the walbro wj65 would work, but a quick ebay search results in Zero for sale. If I search for "stihl 064 carb" I get a couple of hits for various other walbro wj carburetors .
Can anyone recommend a replacement carb for the bing 49?

Just trying to dig up info. Never owned a 064 to know. Only ran friends saw.
stihl 064 WJ-65a 11221200616
Just wondering why would any of the 066 660 carbs work? If they are the newer with that air dam on them just put the old style dia cover on instead.
Just a WAG

More options listed under 064 Walbro WJ 6A

Bing 49 carb info http://www.bingpower.de/download/datenblaetter/type49e.pdf
Question I can find carb kits for bing carb for 038, different carb then put on 064? I dont know either of the saws. (found a post by JJ saying the bing carb on 038 was a bing 48 and is different kit then the oregon 49 kits out there for rebuilding the 48).

Check with member here jockeydeuce last known to have NOS bing carb kits for 49.

Thanks cut4fun. I've seen a few of those wj48 carbs but didn't know what they were for. Based on what you said they are for the pre HD air filter. Can they be converted to work with the HD filter setup?
Sounds like I need to keep my eye open for the wj6a or wj65.

If you would like to run the HD filter set up you will need a new filter base part # 1122 120 3411 and filter cover part number 1122 140 1001. The part number for the flat metering cover is 1117 121 0800 for the wj-65. The walbro part number for the flat cover is 21-3135. You could also use a wj-67 no limiter caps and is for a 660. Should work well may have to change the fixed jet. You can get a carb for the hd filter set up and use the flat metering cover off the carb you have now. There is also a tillotson carb HS-320A that is a replacement for the wj-67.the tillotson is a fair bit cheaper then the walbro. You can not get the tillotson from stihl. If you wanted a new carb. Weather the carb is for a 066/660/650 it should work out just fine.

Thanks for all the good info guys! My local dealer had an old wj48 that he gave me to try out. Does anyone know what the difference was between the wj48 and the 65? My dealer didn't have much info. Externally they look identical. Saw seems to run fine after installing it.
-
I am not real sure the difference but there is some info to be had at walbro's webpage.

I have a bing for an 064. I haven't pulled it apart to see if it's good or need a kit.

The last time I was able to buy new Bing kits from Bing itself, they charged me $42 plus shipping and they told me at that time, that the supply was down to six kits in stock. That was in 2006. The Bing is actually the best running carburetor stock for the 064/066 but most of the WJ carbs are fine and that's your best option for replacement on the 064/066/650/660.
