Your engine is actually a model B (seven head bolts--mod. A only had 6)inboard marine engine, and I believe the gearbox is also a B&S product. Since the data tag is missing, a rough guess places your engine between 1940-42. The flywheel will have a 2 digit date stamp on it that will help narrow that guess down. Nice find!

Magneto plate also has date.
Be careful handling that tank bracket, it will break easily.

Default Re: Another newbie find, briggs "A" with marine reverse gear

jester seems tobe right on with dating it. i pulled flywheel and it read a, circled "E" circled "4" and a circled "41". the back of the mag plate had a circled 2 instead of the 4. so early 41 should be its age. it turns over easy now that the exhaust valve is unstuck in the guide. how hard will it be to get the parts to restore it? does the carb look original? thanks for any help.

Nice find! Maybe someday I will be able to find one of those
I have a few parts for the engine, so if you need anything let me know.

Look around for another model "B" for your missing parts. Or put an ad request on Harrys advertisement link.

Flo-jet carb parts still available from Briggs & Stratton. Yours is the "medium" size with 3 bolts holding the two halves together. They sometimes show up on eBay. But they often need only cleaning to keep them from leaking.
Make your own gaskets from heavy paper.
Don't forget to remove the main nozzle before separating the halves.
Sometimes the throttle shaft is worn out, thats also fixable

The magneto will need cleaning of contact points and likely a condenser. any automotive type condenser will work. The coil is usually good. Replace the spark plug wire with new wire core.

mschreiber,

What you have here is a Briggs Model BMT ( A Briggs Model B with a Marine Transmission, I have seen a Briggs AMT before, transmission is similar.)
as far as I know the Transmission was made by Briggs & Stratton. I will have to check my parts book at home and get back to you.

Default Re: Another newbie find, briggs "A" with marine reverse gear

mine pictured above is missing cooling shroud/housing and starting hardware. now trying to gather parts for this machine and wondering if the marine units were built handle and/or rope start. the magazine ad above doesn't show enough for this briggs newbie to tell. is there a way to tell which start method mine had with what is left. maybe different bolt pattern handlestart opposed to rope start shourd? the only thing left on the crank was a small gear which i think both methods used. anyone have any pics of other amg's or bmg's. different magazines ads would help too. thanks.

I thought the small gear on the crank shaft would mean it was a hand crank start. - I have a cast iron hand crank shroud that may be off an "A". It is not in the best of shape (rust, & good size 'chip' (like 1"x2" as I remember)), but it would work fine. If you are interested & we can match it up to be the right size by dimension I'd be glad to send it to you for the shipping cost (free + shipping).

M,

Most excellent engine!

A philosophical point: At one point in history, this unit had come off an assembly line…new, fresh. Quite literally, some worker swirled a clean rag over it before crating or boxing it up and admired what was "high technology." Even though there was some automation at Briggs in the 40's (I think that the history of B and S book claims that NATCO indexed milling machines were installed to do block milling in the 40's), most of the work was done by skilled labor.

I hope this one gets restored. I have a soft spot in my heart for A and B models.

Dang, what a find! Lucky you!

Cheef

With the aluminum head I think the engine is earlier than 1942. There was more important uses for aluminum in 1942 than small engine heads. Namely AIRPLANES. I have a 1934 Model K with an aluminum head BUT the 1942 Model ZZP special, Military shielded ignition has a cast iron head. Both of these engine were made in May of their manufactured year.

It looks like your engine has a compression release on the valve cover plate. I have 2 Briggs model B engines, both have handle starters and they both have a compression release on the valve cover plates. Here is a parts list for the model B.

Default Re: Another newbie find, briggs "A" with marine reverse gear

i just got "b" parts pages from ebay and determined if it came with decompression its a handle start motor. also the gear on the crank is another giveaway i've learnt. now i'm trying to find out if a 46 "a" cooling shroud and crank starting parts will work on this 41"b". i don't have any "a" parts pages. the reason i'm looking at the "a" parts is that they're in very good shape. the "b"and trans are now in indiana and the "a" parts are here in ma. thanks for any help.

I think this may be what you are looking for...
Ebay Item # 190254275050

IF that is indeed a model B crank start shroud. (i'd ask for a few certain dimensions before I bought)
I belive the number that is given in the auction as being on the inside of the shroud is probably a casting #, as it doesnt match any of my part #'s for shrouds in my book.

thanks, that # ain't in my book, i'd think they'd cast a pn rather than not.
