That's what I did, works great.Knock a old plug apart, get a hose barb that fits pretty close and epoxy the two pieces together.

They work well on the intake between the carb and manifold tooi would also get a couple of these for the ex side http://performanceoutdoorequipment....ts/rubber-sealing-wedge-exhaust-sealing-wedge
Thanks for the heads up.It makes it a lot easier to remove the insulator from a spark plug if you grind away the round edge of the plug body where it meets the insulator.
