With all fuels, I normally use tree filters so fuel flow passages stay clean:
one in my fuel fill bottle
one in the fuel fill line of the plane
one in the fuel line to the carb

This prevents any debris from upsetting my mixtures, be it glow ar gas engines.

On the combat starting grid, I seem to be the only one that starts his engine, rev's up, shuts down and then waits for the others to finish their needle adjusting, and waits, and waits.
Before I used triple filters, I often noticed a small lump of fibers inside the spray bar, or a fiber mat in the internai walbro fuel filter. These now are things of the past.
