Hi all, i am new to this forum, good job to all and very thorough.
I am after the part number for the air filter on the SB dip 430 with the Briggs 3 HP.

Sorry to be so blunt, but i am about to go out, so look forward to talking some more!

Thanks in advance.

Hi there can you give us the model-type-code off the engine cowling to give you an exact part number

Cheers.

Hi there Joe,

The Model #is 80202
Type 0880 01
code82022303

Thanks for your help.

gravelman,

Have a look HERE or use the search box and type in these numbers 27987 (foam Filter) or 392308 (paper filter).

Bruce, Thanks.

So 27987s it is then.

Cheers to you.

One more question guys, i have the filter now, and there is a note in the pack saying to soak in engine oil first. What would you use? i would use foam filter oil.

Cheers.

I've personally never heard of foam filter oil. The Briggs & Stratton overhaul manual says engine oil - the same oil you use in the sump of the engine. It does eventually destroy the foam (after quite a few years) but a car-washing sponge only costs $2. If you know of an affordable oil that is kinder to urethane foam than engine oil is, that might be worth a look. The essential thing is that it coats the entire foam block, and then is sticky to passing bits of dust and grit.

Thanks Grumpy,

Yeah i see what you are saying, i have a couple of different foam filter oils i have used for motorbike filters over the years. It actually doesn't hurt the foam at all, but is much stickier than sump oil, and may not suit the B&S engine i guess.

What do others think?

Hi gravelman, I personally have always used 4 stroke engine oil (the same as used in the engine) and found it satisfactory.
The main thing here is as grumpy said, to catch dirt and dust.

A wise old mechanic once told me "The sponge filters and oil are cheap, engines are expensive". So the rule of thumb is to change both regularly to increase engine life, especially in dusty and dry conditions...(which is most of Australia)

By the way gravelman, a big warm to the forum. It is good to have you aboard.

Does anyone actually use proper filter fluid on their Briggs & Stratton at all?
I would prefer this option as it will allow the re-use of the filter element.

The B&S owner manual and service manual both say you should regularly wash the foam element with liquid detergent and water, squeeze it dry, saturate it with engine oil, and squeeze most of the oil back out of it leaving it damp with oil.

I've found that filter elements that have been treated this way for twenty-five years or more are likely to fall apart, but it only takes ten minutes to cut a new one out of a car-washing sponge.

Hey grumpy, here's a tip for ya, the best tool for cutting the sponge to size is an electric knife the missus uses in the kitchen for the roast lamb and beef.
P.S. A good idea not to tell her or

Thanks Darryl, we used to have one of those but I haven't seen it in ten years now. After all that time if I find it, it's mine! I'd be doing better if I even took the time to grab a sharp knife - I seem to keep using blunt ones.

Well guys, i decided to use the foam filter oil, and it still runs well. So my thinking was that why not use a product designed for this job - i am sure engine oil works fine, but as the label says it is engine oil.
Actual foam filter oil is tackier and is also designed to allow good airflow thru the filter while arresting the maximum amount of dirt and dust.

One other thing, how much should i pay if i can find a catcher for my mower?

Regards,

Scott.
