Re: shelf life?
Buddies had similar problems, but I never did. Coming home from a ride I would fill the tank of my CB1100F at a nearby gas station, turn the fuel valve off and ride home on the fuel in the bowls.
In the driveway I would hold the revs at 4000 until the engine stalled, then opened the bowl drain valves and let the final few ccs drain out.
If you don't do this the fuel in the bowls will evaporate and leave deposits. Do this enough times and your carbs are gunked up.
Too bad car carbs don't have bowl drain valves, but you can rig up a syringe to extract remaining fuel through the bowl vents, then add fuel the same way the next time you drive it.
