On that engine you will normally find all engine numbers on the valve cover or engine shroud. If you can’t find them look on the bottom of the valve cover, as someone may have installed them upside down.

Unless I an blind that is an opposed twin L head engine and has no valve covers. Look at all the engine covers for the model type and code numbers. I have seen them in various places on those engines.

figures the one side the engine cover is missing is probably the side with the numbers. Anybody know is there a starter that fits a few models like this? I got on Amazon looked at a bunch. The mounting brackets are all 90 degrees and it looks like I need one with it just flat. Starter is missing on this engine and I have combed it cannot find any model numbers anywhere.

To me it looks like a Briggs opposed twin engine. If that is the case, there are three possible starters used on that engine. Also means the there might be a ID plate riveted to the red blower housing. Do you have this cover and can you post a picture of it, plus the side of the block where the starter mounts?

Being a vertical opposed engine it would use this type of starter.

Stens 435-307

Mounting bolts (screws) are under the flywheel.

Briggs put out a "Twin Cylinder L Head " repair manual which covers all variations of the opposed cylinder engines.
A quick flick through will reveal which variation you have good enough to order parts with
There was only a dozen or so modles and all of them have the same general specifications
The only real differences are the manifold / carb & air filter / Starter / controls ( ignoring the crank orientation )

some had the plate riveted to the top of the blower housing and some had it stamped into the cover on the starter side of the engine.

of course the blower housing is missing. I will grab a starter like the ones you guys showed me and thanks a ton for all the help!!!!!

Since that engine has a cast iron intake manifold, it will be too old to have a tag riveted to the top of the cooling shroud. The number would have been on the cooling shroud covering the side of the cylinder to the left of the picture when facing the intake manifold, #1 cylinder. Well, it appears to be a hybrid since it has plastic cooling fan, so maybe had a tag. With a cast iron intake manifold, it should not have plastic cooling fan. Of course it is an "L" head so will not have numbers on a valve cover. Can't tell if it is a 40 series or a 42 series.

Vertually any B&S starter will work on that by changing the end mounting plate. The mounting plate for these often wore the top bushing oblong shaped letting the armature rub on the windings so check that on any replacement. While a replacement bushing is not offered by B&S, you can get one close at farm supply or hardware and easily adapt it for a replacement.

I can send you a Service Manual covering the engine IF you like, address below put in proper format and remind me what you want.

You can not tell from the physical appearance of these engine whether it is a 40, 42 or a 46 series engine. While some parts will interchange between the three, not all will obviously since the hp varies considerably. I doubt it is a 40 series.

If the parts search gets tougher check eBay and craigslist for sources.

Not sure if this will help you or not but I have a 19.5 hp B& S boxer, looks like yours with cast aluminum intake manifold.

Model 42E707 Type 2275 E1 Code 0106115A

The engine # etc. on mine is attached with a riveted tag to the top engine cover. Good Luck.

If you have not already done so:
I would do a leak down test on the engine before throwing any green backs into it for parts. The leak down can be done using a source of compressed air.
If you decide on a starter DBelectric on-line has good starters and that type starter used the fiber gear. (look at the aluminum flywheel ring teeth really good and if any are distorted the fiber starter bendix gear will not last very long.
Those are good old engines when all is correct, but they are also know for the valve seats popping out which results in 0 compression on one cylinder.
I have a fix for popped valve seats on those that is a permanent fix other than peening. (and can be done with just the head off the engine.
Them type carbs had the fuel pump on the front of the carb, termed 3 screw and 4 screw type fuel pumps with 3 screw the later style. I also have a mod for converting those carbs to a external pulse fuel pump. (the on carb fuel pumps were a source of future trouble and kits getting expensive where as a pulse pump can be found for $10 or less.

As Walt Conner says a Briggs twin L-head service manual is what you need as it shows complete pictures of parts and repair.
ebay is a good source to review pictures of the parts also opnce you know what you are needing to review..

if you can tell us whattractor model number this came off of there will be info on the engine hp rating which can help identify the model 42 or 44 or 46...

Only one problem there as some Craftsman mowers that used the 420000 series even with same type numbers were label as at least three different hp rating. I know definitely to this as I had three Craftsman mowers in the my shop the same week that were label 18.5, 19.5, and 20.5. All three were sitting side by side.

But if a Craftsman then the owners manual might give us a model number. The problem there is the engine maybe a transplant engine so that may not even work.

HP rating decals on mowers mean very little. Towards the end of the run of "L" head engines due to Government emissions restrictions, B&S was plastering all kinds of HP ratings on the left over engines. I have seen 46 series engines with 16.5 hp stickers on them, originally called 20 - 22 hp. Same is true of the 28 series "L" head engines. Usually if it has a .5 hp attached to the hp, it is an oversize engine. While B&S got in trouble for over rating their engines, no restrictions on under rating them.

Had a customer years ago that had the 40 series on his mower with the 12.5 hp sticker.
