I have used Walbro felt clunks in my gassers but I'm not sure if that's what would be recommended for a turbine as I've only used a UAT or the MAP headers. I got the Walbro at a lawn mower repair center. It't the one with a metal clip holding the felt portion to the clunk and will obviously just clear the standard size opening of a fuel tank(other models are bigger). I've also seen it a Home Depot but it's sold as a package and comes with two other items like engine oil and something else for about ten bucks. Was about three or four bucks seperately at the mower shop .
