Re: Carburetor Float valves
New valves may have brass shavings inside from machining.
1. Before installing, blow 30 pounds pressure air backwards through the OPEN valve for 15 seconds or so.
I say 30 pounds because that is the pressure of an "OSHA safety" regulated nozzle.
2. I suspect that if 100 +pounds were applied to Viton valves that the plastic retaining ring might be blown out of the valve.
3. Also installing a "finger" filter in (the gas tank shutoff valve) keeps dirt and rust out of the float valve. Which is a common cause of float leaks
4. The finger filter keeps Dirt and rust from getting inside shutoff valve which makes it hard to turn and wears it out.
