While I agree in general RE: steel fuel tanks and rust issue, I would not agree RE: if manufacturer felt it needed a filter part, citing that aggressive cost cutting measures @ play with B&S...and there's really the need for at least a mesh filter in their line of side-draft, lower emissions flathead engines such as 500 ~725 (with 675 being the most common one out there).

you should have a pre filter in the gas cap, Doesn't it? mine does and we only use ethanol free gas to avoid corrosion I hope.

675 series doesn't have any prefilter on the gas cap.

Also: plastic tank, etc. don't really care much about E10 or not gasoline, so long as there's no water in the gas(due to storage and/or fuel handling, some water may get into gasoline dispensed from fuel pump), your carb will be fine.

Afterall: regionally speaking: we've been on E10 for over 3 decades now, local has no complaints about carb corrosion, etc. including OPE engine users. If Ethanol is "as corrosive" as you want to believe in, then the public hysteria and local news media(who luvs to make a big fuzz out not of nothing just to sell more papers)would have caught on...

Bottomline: I just need a mesh filter to protect large debris from getting into the fuel bowl and anything (debri-wise) smaller than the jets and orifices used within the carb will get through w/o the risk of clogging the carb.

No need to go overboard on this matter (my take), for I've used coarser mesh filters (currently on the B&S red on my 675 mower engine) w/o issues.

Q.


Well my neigbhor have a push mower with the 7HP briggs and plastic tank, always with problem and taken to the "shop", one day she ask me if I can take a look and I did, the main jet clogged, blow clean put back, works fine, two weeks later the same, cleaned again, three weeks later again, this time I added a pleated filter and a shut off valve, with that firm instructions on using only ethanol free gas, stabilizer and to shut of fuel and let engine die from starvation when she is finished for the day. 2.5 years later the mower starts at the second pull most times if not at the third.

 

[Quest]

was your neighbour doping gasoline (before the incident) with fuel stabiliser before? or it just ever so happen that after you helped her, you started instructing her to go ethanol-free gas + stabiliser?

A controlled experiment (e10 with stabiliser, then e10 w/o stabiliser) will prove the point.

Oh and BTW: stale gas will gum up the carb, regardless of ethanol or not.

I use the Briggs & Stratton filters. They are a quality item.

FYI, the white filters are for fuel pump systems and filter down to 75 microns.

The red filters are for gravity fed systems and filter down to 150 microns.

I wouldn't consider the ops fuel filter to be a long term solution, maybe 3 years tops due to the paper media. The Briggs filters will last 10+ years.

I like those Briggs filters. The are nothing more than a screen which its passages are smaller than a carb jet. It lets the insignificant stuff on through and stops the bad stuff.

 

[steve20]

I've always used the pleated filters on my gravity fed engines. In fact, I took off one of the red filters on a 10hp Briggs and replaced it with the pleated filter. It's been years and there have been no problems with it. Guess if I run into fuel starvation issues I'll know where to look

I have just found a source of E0, so now I will use E0 for all of my non "car/truck" engines. Stabilized of course with blue Stabil.

A sintered brass or screen type would be a better choice.

I have been running one of these on a GCV160 for three years going on four. No issues yet. I may replace it this year though just on GP.

Please add the part numbers for those two filters, and the name of any store that stocks then such as NAPA, Pep-Boys, Advance auto parts, exc.

BTW, thanks for the info regarding white = 75 microns for use with a pump, and red = 150 microns for use with gravity fed / no fuel pump.

 

[JimPghPA]

The red (150 micron for gravity fed fuel system) appears to be 120188 partstree does not stock that number but list MTD 298090S and troy bilt 298090S

The white 75 micron (for systems with a fuel pump, but apparently not to be used after the pump because it might not be able to handle pressure) appears to be 120014

 

[AandPDan]

For gravity feed, 298090S is the Briggs number. 120188 is a Stens.
With a fuel pump, 394358S is the Briggs number. 120014 is a Stens.

Advance Auto, Home Depot, Lowes, and Walmart all have similar models.

Ebay and Amazon, along with almost any OPE shop will stock the OEM. They're usually fairly cheap.

Lowe's carries the B&S red filter in a single pack. It's B&S's part # 298090S for the single filter pack. I believe it was around $3.

I live 2 hours from the nearest lowes or Home Dept. Just went ahead and order a pack of 5 Red Filters from ebay. For the New Snapper.

Free Shipping @ $15-->Figure these would last at least 10 years.

Pretty cheap investment.

Thanks Dan

Me too. For whatever reason, my GCV160-powered Husqvarna mower kept running into clog/stall situations as sold. Haven't had a single problem since.

I might do an simple experiment and purchase a 75 micron White filter and install one on our new Southland roto-tiller with a 159cc Briggs motor.

Local Tractor Supply has them but much more expensive compared to what I can get them from e-bay.

But I agree 100% todays lawn equipment that you buy new with the plastic fuel tanks should have No issues with particles clogging up the carb. Unless your newly purchased gas supplies them. Keep your {Plastic} fuel jugs sealed at all times.

The Red 150 micron filters {Should} be all the filter you would need.

Now if you had an older model mower with a metal gas tank or use a metal fuel can? I would consider the White filter first. Hopefully with No issues.
