You should be able to get sea foam at napa or auto zone. I used it on my truck, which is carbed, just pour it into the carb, let sit for about 20 min, then fire it up and wait for the smoke show (Wow, does carbon build up smoke!!). Does a good jod of cleaning all the build up, and gets rid of those sticky butterflies. I also use in it my other car, which is fuel injected. I take a old soft tooth brush, take off all the intake crap, scrub it out. I also pour a small amount down the throttle body. The bottle doesnt have any warnings on it about using it on a f.i. motor, but I go pretty easy on the amount I use. This sh!t is pretty versitile too, you can add it to your crank case, and/or gas tank too. Price aint to bad either, about 6 bucks for a quart. They also make this stuff called trans flush, for automatic trannies (Bottle also says that it can be used to douche out your power steering system). Used it on my 350 before I changed the gasket, did a good job of cleaning all the crud out of the transmission. Mofo runs like a dream now.!!!!
