G'day folks,
Thanks Jack, pretty sure this motor would be the 141300 series, would you risk a guess at year of manufacture?
Randy, it's interesting to find a 'serial number' - Briggs started to use a 'Code' rather than serial numbers around 1964-5.
The 'Code' is made up of a 6 digit manufacturing date [YYMMDD] followed by a one or two digit factory/plant location code.
So your engine is 1958 - early 1960's era, and maybe pre August 1964 if it has a Serial Number, not a Code.
A bit of info:
https://www.smokstak.com/forum/showthread.php?t=106744Thanks AVB, I had a lot of trouble with the key, I have just used a piece of 3/16' key steel with a lot of filing.
Using steel flywheel keys is a major no-no on aluminium Briggs engines; they intentionally use a soft metal key - aluminium or die cast zinc alloy.
This is so that if a sudden event [object strike, part failure] brings the engine shaft to an abrupt stop, the key will shear and: 1. Stop the engine firing, by altering the ignition timing 2. Protect the keyways from damage.
If you think the nozzle I have is the correct one, and fits all the way into the carburettor throat I will try to work out a way to get it to seal.
I'd say it is the correct one. This a a 'two-piece flo-jet' carby, and there is a cutaway diagram on p45 of the Repair Manual which shows the parts. The nozzle is designed to seal metal-to-metal, by the look of that, as AVB has said.
The manual you need is Briggs P/No CE8069, and you can download a free PDF copy [~21Mb] from
HERE.
I just hope that the nozzle hasn't got bent - it should be removed
before taking off the carby top.
Do you know what head bolt tension is likely to be?
165 in-lb is the Repair Manual spec for this model.
Unfortunately, there doesn't seem to be a parts list download available for this old model - the B&S search page I use recognises the Model/Type info, but doesn't have any docs available for it.

https://www.ereplacementparts.com/images/briggsandstratton/141300_Series.pdfLooks like carby overhaul kits are still available from various suppliers, P/No 291691. OEM kits ain't cheap, though.
Flywheel key has current P/No 222698.
