Never opened a red or white pancake filter. What are the micron specs for both ?
The pleated filter shown above I have used many times on carbureted VW engines with no problems.
Can't see a problem with a carbed lawnmower engine.
Had to laugh at the Briggs 691035 filter. The element looks exactly like the filter used in many GM carbs.

Those filters are proven to work on 6 and 8 cylinder engines for many years.
Me I would just use the inline paper element and not worry. Gas tank is clean and also the gas and your good to go.
