Homelite BP-250 Blower IPL 18421 has a diagram of a WT series carburetor similar to the WT-212A that is used on this machine.

Homelite BP-250 Blower IPL 18421 has a diagram of a WT series carburetor similar to the WT-212A that is used on this machine. Thanks, I know you're really trying hard to help me but I just spent a half hour trying to figure out where some video that has something in the title or in their hyperlinked image saying Homelite BP-250 Blower IPL 18421. And you say here that it only shows a diagram if I ever find it? No video? Can you give me some more specific help please?

Sorry no video, it's an Illustrated Parts List (IPL) .I'm not sure how to post a link to it, but you can download a free copy from leonschainsawpartsandrepair.com, then click on parts diagrams, then on Other Homelite Equipment IPL's...BP-250 blower IPL 18421 is on top of page.

Thanks. I sure wish you'd found a video. It does look like you were able to include a link to take me to that IPL file of images after all. That helps. Thanks. Is there anything special I should know about next week when the parts get here & I start the job? Hopefully I can do t all in one session so I don't forget anything about how it goes back together. 😉

Are you sure mine has a Walbro carb & not a Zama? My carb has 4 screws on the top plate like the Walbro does in this image, but the top of my carb is square like the Walbro on the IPL’s Carburetor page, but there's no primer bulb on top in that page's pic of the Walbro like mine has. That is a little confusing. I do seem to remember way back in that other question of mine that I'd pulled the carb off after I was told to do that so that I could find the part # on the back. Heck, I think I even took the carb off back then to see the PN on the backside & picture of it now that I think about it. You or someone else here had told me in my other long question that I could find the PN there on the side opposite the fuel ratio adjusting screws.

That looks like a Walbro to me, but yes should be part numbers on the opposite side. I think the IPL is inverted for the walbro carburetor, showing the primer on the bottom, not sure why but these carbs can run in any position so may just be the way they decided to print it.
Here's a few tips: Dissassembly: If you have a digital camera or pocket-computer, it is nice to take pictures as you dissasseble, each time you remove a part take a picture, that way if there's any questions when coming back together you can refer to the photos. Make sure you remove the adjustment screws to clean out the passages there, as they are some of the smallest.
Cleaning: I recommend using a good carburetor cleaner (I like aerosol seafoam but everybody seems to have their own favorite), and make sure you clean all the passages. The IPL should help with this. Some of the passages are small as a pin and can be easily overlooked, especially if they're badly gummed up. I like to use a torch tip cleaner set if badly gummed up, but be careful as you can damage the carburetor fairly easily. I then finish up with some compressed air, pretty low like 10psi to make sure all the passages are clear.
Reassembly: I like to wipe all the gasket surfaces down with brake cleaner and make sure they are clear of any old material (may need to use a scraper, I recommend plastic to avoid gouging the surface). Screws don't need to be superman tight, provided the gaskets are good (since they're new) and all surfaces clean should just need to be a bit past snug. Take your time and make sure everything is there.

Thanks, I wish I could find the picture I think I took of the PN on the carb's backside, but I can't find it. This doesn't sound too tricky except for knowing where to look for crud to clean out. You're right about the Walbro being upside down. Now that you said that, I see PN 21 at the bottom looks like that Primer Bulb & is called that underneath it in a short list of parts or kits. This is silly but no hardware stores around here cater to people that want to fix weedeaters, chainsaws or gas blowers. I looked. Home Depot has it online but the want $5 for 10'. Could you tell me if the smallest size on this page, the 1/8” ID, is what I need? I'm asking so that I can get some before I start working on it. Getting 10’ of it is ridiculous for me but I guess I shouldn't complain since it costs less than $5. This ¼” OD x 1/8” ID x 10’ Micro Fuel Line is manufactured with PVC. It is resistant to weathering, tearing, ozone radiation, and surface abrasions. It doesn't say alcohol resistant anywhere that I can see but I guess I should just take my chances. That's unless you'll stick the 3 pieces that I'll need in an envelope and mail them to me at 2870 N Roxbury St, Orange, CA 92867. I could send you $1 or whatever? www.homedepot.com/p/Everbilt-1-4-in-O-D-x-1-8-in-I-D-x-10-ft-Vinyl-Microfuel-Line-HKP004-015/303132524

I've never worked on a blower so I'm not really sure of the fuel hose size. The size I buy for super 2's and the like (which I assume use the same size) is 3/32" ID by 3/16" OD, or just a hair smaller than the one you posted. If you have a caliper, possible to measure the OD of the lines you have and the diameter of the fuel inlet into the carb? I'd be happy to buy some (only have about 3" laying around) and ship to you, but it costs $1.99 /ft (I assume you'll need at least a foot probably 2), so by the time shipping is factored in it'll be more than what you posted there. You never know you may find a use for it in the future

Do any of you guys know what size I'd need, rowdy, onlyhomelites or 5terrysupersaws? Surely somebody at least has one of these carbs sitting around & they could check it to find out, if you wouldn't mind? And as far as using any of this tiny hose in the future, no way for the intended purpose. Rebuilding this carb is going way out of my league. I'm too old to be doing this. I just turned 60 on 1/29. Maybe for drinking my Diet Cokes if stupid California keeps trying to ban plastic straws since they apparently litter the oceans and they kill far too many critters? 😉 As far as shipping goes, I figure that's just a stamp & an envelope. I'd need to guess that I'd need 2'-3' since there are 3 pieces of tubing that are 6"-8" long each? Anyway, I can either just leave what's on it on or I could buy 10' from Home Depot for $5. 😄

I checked my ST-145 which uses a WT-220 carburetor. The fuel inlets are just a hair over 1/8 (around 5/32) and the fuel hose is 3/16 OD.
I would probably go with the 3/32" ID and 3/16 OD hose.
P.S. I will be rebuilding my carburetor here within the next few weeks as well.

Is that since you think 1/8" ID tubing will be too loose of a fit? I'm not doubting you but I'm just trying to understand your thinking before I buy 10' of it to try and I take things apart.

In my eyes the 1/8 would fit fine but the 1/4" would be too big to go into the gas tank. I did put the 3/32 line on the carburetor and it fit, albeit very tightly

So, if the 1/4" OD won't easily slide into the holes in the top of the tank, then the smaller 3/32" OD tubing is what I need to get. Thanks. Here's an off-topic question: Is it better for you regulars here if photo Attachments are added into a reply by clicking INSERT after browsing to them or by just attaching them by clicking DONE without INSERTing them? Maybe it doesn't matter but it might differ depending on if you access this site on a smartphone or on a PC. I've noticed that if you're using a smartphone, you can't Add Attachments. That option is only given to you on a PC. I'll INSERT this one:

The carburetor is 100% for sure a Walbro WT-212A. Rebuild kit: Walbro K20-WAT The vinyl line shown from homedespot in the link is unsuitable for this application!. (It's a water supply line) Original fuel hose part#94772-32 is 1/8 inch ID. Suggest replacing with Tygon fuel hose (.125" x .200") two 8 inch pieces, and replacing the fuel filter part#49422...Leon (onlyhomelites) has the filter and maybe the fuel hoses. Have you watched any of the carb. rebuild videos that undee70ss provided a link to ? Just to get an idea of what's involved..

I should probably get those 2 hoses and the filter so I can replace them while it's all apart since I don't want this to be a long drawn out thing where I might forget something. How do I reach him? And yes, I did watch some of the videos at www.youtube.com/results?search_query=walbro+wt+carburetor+rebuild+instructions that undee70ss gave me early on page 1 but I searched thru all that I could and I never found any for my Walbro-WT-20, only for WT-10 carbs. They were interesting & I learned some things that should help but I'd still really like to see a good one for my WT-20 it I could.

This might be a dumb question but would a blower & a string trimmer both use the same length fuel lines i.e. is the tank mounted in the same location with respect to the carb?
