Need Carb Info

Long story short. I have and old Snapper mower. It's worth maybe $150 tops. The carb is shot. Rusted out. it's a Walbro 5 4993 No other number visible. Early 80's model I'd guess. Anyone know a good cheap replacement and the model #. I've searched the Briggs site. no help. Even using the Model Type and Code. I guess it's too old. Seached E-bay and Amazon. All I've found is either later model 5 4993's or kits for late model 5 4993's

Thanks in advance.

Thanks, for trying to help. Bottom line. Is there a replacement model- Non OEM for a 70's model no frills Walbro 5 4993? The carb is on a 10 HP flat head Briggs. The engine Model,Type, Code is printed on the fly wheel cover which is not likely original.But I'll give it up if necessary.

Thanks

Walboro and Tillotson are two I would consider for replacement. They are of high quality but unfortunately expensive for a old $150 mower. There are also many clones being imported from China under other brand names that would be cheaper but I have seen some so poorly made that they just can't be made to run properly.

Thanks Dane. And El Cheapo carb that will get me thru the season is what I feel I need. Hope I can up-grade to a better mower next year.

Using the Model-Type-Code as requested by Briggs. I got nothing. Will someone be kind enough to help with the Carb part #?

Model. 254707
Type.0124-01
Code.92022831

Feel free to include links to new less expensive carbs that will interchange with the above mentioned.

Thanks. IH

Hello ih4630,


Can you post pics of this carb or find some that look like it on the net ?

Can you explain what's "rusted out" on this carb making it non usable ?

I haven't seen a carb just like it on the net. I'll try to remember to take pix next time I have it off. As for rust. The bowel is really bad. The jet housing,( maybe not the correct term. I'm new to this.) Had a lot of surface rust Even after cleaning it. And the main jet was seized so bad it stripped the head when I tried to remove it for cleaning.I sprayed both ends and thru it several times with carb cleaner. And was careful to use a screw driver that fit. And applied as much downward pressure as I could muster while trying to back it out. No go.

Hello ih4630,

Does your carb look like THIS one ?


If so, The rust stains on the "jet housing" will not hurt a thing, The rust in the bowl will not hurt a thing as long as it's not flaking off or leaking from a pin hole.
Jet seizing in these old carbs was common, As long as the jet is clean and fully open the stripping will not hurt a thing.

You can still purchase a new float bowl part# 221995 and carb rebuild kit part# 394698, They are also available in aftermarket as well. As for a new carb, It's no longer available from Briggs and I haven't seen a aftermarket replacement.

The biggest issue with this style carb was worn throttle shafts, Once worn the engines wouldn't run correctly. But having low and high speed adjusters one could get the engine running well enough to use.....


Good Luck

Thanks for trying to help. No mine is a later model than the link you posted. Mine is the carb Briggs used till they went with the over-head valves. At least it' it's all I've seen on the Snapper SR-10 and 12 hp Briggs engines.

FWIW. I put mine back on the second time. And it's running great. Don't how long it will last. A couple of questions just for my education.

So it's not necessary to remove the big jet. Just be sure fuel flow's freely thru it? I was thinking there might be other small holes in the big jet that would need cleaning?? Again this is all new to me. Just trying to learn.

Also this carb has no seat for the needle. Not sure if the seat is missing. Or if it designed to not need one.I bought the mower used. The float and needle seems to work fine without a seat. Again just trying to learn.

Thanks for the education. More is always welcome.

IH

Hello ih4630,


No small holes in the side of the jet, Now there is small holes in the emulsion tube under the jet but seldom do they get clogged where carb cleaner shot through the center wont clean.

If you look at the tip of the float needle valve you will notice it has a viton (rubber) tip on it, With this type needle all that's needed is a clean smooth seat.....

If you can post the Snapper model number which should be on the back of the machine or on the center tube/frame under the seat, I may be able to track a engine model number down......
