Finally got fed up taking lawn mower main jet out and cleaning it so mower would run. Bought a filter at O'Reilly Auto Parts today and installed it. Hope no more issues!
Do you guys usually run fuel filters on small engines?

Was out of carb cleaner when I grabbed the CRC … found it a better blast than the cheap cleaners I normally buy …
started second pull …
I always add a filter. The one in the tank may not work well enough.
Mine would always do that. I started treating the fuel and all my problems went away.

Putting so much additive in gas cans that additives might need filtering …
Let me know how you add a filter to a tank mounted carburetor. I'm all ears.

With any carburetor problems I take the whole fuel system apart and clean it, including the fuel tank. Then I try to not introduce any more contaminants. Some of my OPEs have a fine mesh filter at the fuel tank.
yes, briggs has two colors, red filter is for engines without a fuel pump I think
I like to add a clear filter whenever possible. Usually for older machines, I swap out the lines for transparent Tygon stuff, it's also convenient to be able to see fuel flowing. I put them on all my bikes too!
Throttle body cleaner and a good winterize would solve that issue.
I run filters on all of them, mainly because I'm surprised at the amount of junk that seems to come out of gas pumps and into the cans.
With that said, 90% of the carburetors I have to clean for customer small engines are gummed up due to varnish and bad fuel. Something that can't be solved with a fuel filter.

I ordered an assortment of that hose and will give it a try … sad how many times I have trouble with an engine over poor quality fuel hoses …
The filter I got at O'Reilly looks like this..

On my dad's tractor mower he we put on a wire mesh type serviceable filter. Got it from Ali-Express. It did so well I put one on my lawnmower too. They are meant for small-CC bikes but they are perfect for this use too!
