Any one know where the oil drain plug is on this model. Or is it one that you do not change the oil in? Got it for free and just trying to clean it up. Can't find anything on the underside after cleaning it up

That model number didn't show up in any searches.... The Engines model would be helpful, it should be stamped into The metal cover on The engine, either above the spark plug or over the muffler.
if it has the engine im thinking of, there may be a drain plug under it, that accepts a 3/8" drive ratchet to remove it. Or you may just have to tilt it over and dump it in a pan.

Well I found the engine number finally. Went on the B and S website and downloaded the service manual. There is no drain plug . The oil has to be removed from the top of the fill tube. I copied part of the manual as follows:

Remove Oil The oil must be drained from the top oil fill tube (E, Figure 10). 1. With engine off but still warm, disconnect the spark plug wire (A) and keep it away from the spark plug (Figure 9). 2. Remove the dipstick (G, Figure 2). 3. When you drain the oil from the top oil fill tube (E), keep the spark plug end of the engine (F) up (Figure 10). Drain the oil into an approved container.

Then the Briggs has the service manual or IPL info wrong as the IPL from the Power Distributors website clearly has item
listed as being there.

And it is also listed both the sumps for this engine.

Two distinct opinions on this.
Some ( myself included ) use a sump pump ( B & S Even make one )

Others are ardent that the only way to do it is to tip the engine

Decision is yours.

It is noted that there are applications where even with oil plugs require an extractor to used due to an inaccessible oil drain.

I'd say the IPL is wrong as I've removed lots of mower drain plugs and the only bolts of any size were the 3 holding the engine to the deck....unless its one of them. Previous owner also said he had to change oil by turning the mower over. In any event after sitting in a shed for 3 plus years with gas in it. New gas, oil changed and disgusting air filter cleaned....starts with one pull. Now it belongs to my daughter.
Thanks to everyone who offered their assistance.

Weedeater Lawnmower,

Let me know when you get to the point of starting this puppy... I have a similar Model 500 and can't get it to run except by feeding gas through the carb. Of course, it only runs a second or two and then shuts off. I've changed spark plug, put on new carb kit from Weedeater (while it was still under warranty, they sent me one), checked the flywheel key (it's good, I never did hit anything with it) and it still won't run.
This was only after owning for a year or so, about 5 years ago. I think I posted something on this site about it then.

I liked the lightness of the mower, and my older MTD 22" mower I had for mowing banks finally quit and I'd like to get it going again as it's easier to push on banks than my other trimming mower.

Mower sat for 3 years....changed the oil / drained the old fuel / cleaned the air filter / new plug . It started on the 1st pull and is running fine. Is there an inline fuel filter on yours? maybe plugged? Have you got a good spark?

Got your update and I'm glad you were successful. I re-read my old posts on this mower and I found that I had actually hit a stump and had to have the engine mount repaired - the sheetmetal there was so light it just pulled the bolt-heads right up through the frame. Remember how I commented '... how light the mower is to push.' That's why - not much metal to these Weedeaters; and if I remember correctly, I didn't hit the stump that hard but just hard enough. I replaced the flywheel key at the time even though it was only slightly dented (not sheared).
After the repair, I was able to run it maybe once or twice more before it wouldn't stay running after starting - so, I suspect the stump hit has contributed something to the problem.
In reading those posts from the time, another forum member suggested there was a electrical-shutoff associated with the 'pull bail brake'; so, I'll look at that next.
As far as an inline fuel filter, I don't think so - it's just an earlier model of your mower's B&S engine. The only filter I know of is on the carb's pickup cone that sits in the fuel tank.
Hope to work on it this weekend.
