What are folks using for an inline gas filter on a 26-27 set up. Concerned about the close distance to the exhaust manifold if I mount a plastic filter under the shut off. Any photos would really help.
Another question comes to mind. I have gas seepage at the shut off coming from the front. I wound a piece of teflon string in place of the felt but I question whether it will deteriorate in contact with gas. Any thoughts?

Under the big brass nut that goes into the casting is a leather washer. Get out a big wrench and snug it up but not so tight that the valve lever won’t turn or bind. New leather washers are available (got mine from Lang’s) if needed. I have some pics but can’t upload from my phone. I’ll try later when at home.

Thank you. Right now the piece has a felt instead of a leather washer. I'll purchase one from Langs. Thanks for the tip!

Richard, no additional gas filter is needed. The filter is a screen in the sediment bowl. You can open up the bottom of the sediment bowl to inspect and clean the screen. Uses a lead washer to seal the bottom fitting, reusable if you don't damage it, available from the usual vendors if you do.

Every gravity fed carburetor needs a fuel filter.

There are some who have had their car not run well, so they removed a fuel filter and then it ran fine. So they decided the filter was the problem. The DIRTY filter was the problem. When one removes a dirty filter it should be replaced with a new filter.

It does not take much trash to mess up a NH, hitting a good bump will dislodge trash from an old fuel system. The fuel filter needs to be close to the carburetor to insure that you do not end up rebuilding it.

I like this one:

I think it is the same one Stan Howe recommends:

"No gravity feed carburetor should be installed on any engine with out a good quality filter just prior to the carburetor and a shutoff near it. "

Anyone ever try the glass bowl filter sold for model A's by Snyder's?

You need a filter designed for a gravity fed system. Like riding lawn mowers. A mower shop will have the type you need. Used them for years no problem.

I prefer this screen from Snyders. Fits perfectly in sediment bulb. Just type screen in Snyders web site.

One that takes up very little space, Briggs and Stratton for a 18/20 hp.
