Briggs & Stratton Carburetor help

[jones6780]

So I am trying to get an old B&S engine running. Got it to run just a bit pouring gas down the carb. Took the carb off and soaked it in thinner, got everything cleaned up. The problem is that the threaded piece ( Has a 7/16 hex with external threads, screws into carb and internal threads, jet screws into) is corroded and broke. Now the engine shroud may have been changed as the Model 80312, Type 1524-01 shows a different carb on the parts list. My carb comes straight out from the horizontal shaft engine, has the tank mounted under with 1 pickup tube. There is no other numbers on the carb. The B&S parts website is down and I need help to find the part/prt# to get this running

What is the engine off of..? I'm just wondering if you've tried to find a parts manual for the particular machine it came from. I have found what engine is on several different older lawn machines that way. It may not give the exact engine model number, but will have that particular company's part number listed. Copy and paste that part number to a Google search, and see what pops up.

That type of bolt on carb. was used on a lot of 2 to 5 hp engines. Maybe even do a search for that particular machine. If it's a popular collectible item, you may even find a forum on it. You'd be amazed what people collect...

This advice may not be what you are looking for but I've often found that going online and ordering a new carb is very cost effective vs taking the time to fix the old one.

The engine is on a Marlow Mud Hog, diaphragm pump. can't find any manuals for it. I am not sure which carb will work as the model numbers may be wrong and I haven't found the exact carb. I did order a high speed jet, p/n 299060, but it was too big. That's why I need the correct p/n to order.

Somewhere on the engine fan shroud are model numbers, engine vin number etc. Those numbers will get you to the right parts catalog to look up part numbers.

Have to agree with this. Earlier this week I got online to order a carb gasket for a 10 yr old generator. I could get the gasket for $7 or a complete new carb for $14 w/ free shipping.....it was a no-brainer, I ordered the new carb.

I have the model/type but when I look them up it shows a different carb. Shroud may have been swapped out.

As for ordering a new carb, not sure of the correct replacement. Model/type may be wrong numbers on shroud

From looks of carb I remember a 1-1/2 horse B&S on lawn mower for 60's....

Aught to be a million of them out there... Price seems a little to far out there though... Get part number from "catalog" and do search...

Would not be supersized if this is carb you need...

Your engine looks closer to a 080202-1672 either 01 or 02 type. Carb looks close, but they use the 299060 jet that you are saying is too big.

You could always try checking here. This company seems to be the parent company of Marlow Pumps. Marlow Obsolete Products - ITT CONTROLS

They are located in the Netherlands, but on the contact page, they do have an email address. I copied, and am pasting that email addy here: contact@ittcontrols.com You can copy, and paste in the address bar of your email, and make a request. They may have an archive of old manuals, both parts, and owners they could send back via email, or give a link to it. I have found that most companies are glad to be helpful. A big help is to give a good description, or model a number of the pump would clinch it, if they do have archives.. A few minutes to write, and send an email may find you exactly what you're looking for, maybe more than you expected..!!

Thanks for all the comments and suggestions. I think I have found the carb.
Briggs and Stratton 11--99 - Briggs & Stratton Horizontal Engine (2) Carburetor Assemblies Diagram and Parts List | PartsTree.com

I have ordered another jet that may work p/n 299059. The part I need is 117, but I ordered 681 as an assembly. See part 96A? If the drawing is correct, then that is the defining part for my carb. Parts should be here Dec. 11th so I should find out if I can get this thing running. Hope the diaphragm and flapper valves are still good. A new diaphragm is over $200.00

I will be contacting the company for a manual

Thanks again

That is what I do as soon as I know my problem is the carb. Seems I can never get the jets perfectly clean and new carbs can be pretty cheap depending on the carb. Sometimes only about $25 to $30

Those lil 2 & 3 hp carbs are basically all the same. Pulsajet diaphram along with the fuel mixture screws will be what you need. They're all the same. I know what your going thru to find parts for the old style B&S engines. I'm refrub'n a gokart simple yard-cart and have several 5 hp engines trying to fing carb parts for at least one to get er going.

Are you 110% sure there is not a part number on it?

The 2-3 hose early Briggs engines with the shallow fuel tank had the Vacu-jet carb with one dip tube that sucked fuel directly out of the tank to the jet. The 5 horse and newer type engines have the Pulsa-jet carb with 2 dip tubes, one tube goes to the bottom of the deeper tank and it has a pulsed pump that pumps fuel to a bowl in the top of the tank and a second tube goes to the jet from that upper bowl, so as fuel level in the tank goes down the carb does not lean out with the fuel level dropping like the Vacu-jet did.
