16 hp Briggs-is it a 325xxx or 326xxx

[B.Ikard]

Gents, Looks like I finally have the 16 HP Briggs I have been searching for to repower my 7012!! After a closer look after the fact this engine might not be a 16hp....even though it is advertised as a 16. It is a 325434 0129-02 1971 build. Are the 325xxx 15 hp and only the 326xxx 16 hp? Any knowledge or experiences would be greatly appreciated. Ike

Don't think the code #'s are related to hp. Here is how to decipher the codes: http://www.outdoordistributors.com/Briggs_And_Stratton/briggsmodelid.html I think both the Simplicity 3416's and 3415's (16 and 15 hp tractors) had 32 cu. in engines. Brent

Best I can tell from my briggs books, 325434 is 15 hp. Type 0129 says max rpm 3400. The hp I got from a chart for 325430. The difference between the 0 and the 4 is no starter vs. starter generator. And I didnt think I'd have a use for a briggs SALES book. :D;) when I get a scanner working again, I'll post in tech tips some info straight from Briggs concerning A/C and Simp. engines. [:0]

I have a twin 16hp Briggs. The engine I.D. is 401707. The type is 0132 01. The code is 79031912. Don't know what any of it means. Probably not any help, but the best I can do.

First of all you won't even notice the 1 HP difference. If you turn it up to 3600 RPM you will gain your one HP.

Thanks for the replies. I wondered if the 3400 limit might have something to do with the 15hp rating. Odd that Briggs engines of this family all have 32 cu in but horsepower varies from 13?-to 16. Are there any differences like valve size or carburator? Ike

I have what I was told was a 14 and all I can see is there is no visable diff. between the 16. I have heard the diff. was a smaller jet in the carb. But without looking at serious #'s for awhile I can't qoute the info to you, and I don't want to give you false info. It's just what I've heard.lol

From what I understand alot of the 1 hp rating differences are more Sales pitch difeereces and marketing ploys than actaul hardware differences in alot of the small gas engines made. Look at Sears Roebuck. They sell there engines rated at slightly higher hp ratings than the competition but actually they are the same engines. Their Power tools are rated the same way. Borders on false advertising, but doesn't cross the line. This hold for Briggs anyhow. Sales Gimmicks... With Kohler however, I believe there are actual bore differenced between all the HP ranges. I think Al can shed more light on all this than I can.

Sam they all do it. I have a 2004 Taraus with a Duratec 3.0L engine, advertised rated at 200 HP @ 5500 rpm. I sell a 7.6L Diesel engine advertised 200HP @ 1800 RPM. Which one one will give me about 8000 (280,000 miles) hours life before overhaul? It ain't the Taraus.:D:D:D But is still they are both 200 HP engines. Marketing. Neither of them lied. Also the first word seems to be the key word. 16 is more than 14, 6 is more then 4. That catches your ear, forget detail, until it breaks.:(:(

The first 2 numbers are the displacement.32 means 32 cubic inches.On flathead single cylinder engines take the cubic inches divide in half and that is usually the horsepower.Every 320000 series Briggs I ever saw was a 16 horsepower.

[patrician12]

If you look this engine up in the Briggs manual it is rated as a 15hp.It is the same displacement as the 16,uses the same piston,rod and carburetor it is just rated at a lower rpm.If it walks like a duck,quakes like a duck and looks like a duck its a duck.
