I have encountered my first trouble with this summit four barrel.the power vlave or accelerator pump has failed..i think.I noticed the truck was running very rich and then my mileage dropped to 10-12mpg i was getting a good 15-18.Im looking for a rebuild kit but it appears that the rubber diaphrams are not part of the kit..dammit! years ago when you got a rebuild got EVERYTHING that was a 'moving part'. I dont want to rebuild the entire carburetor it only has 6 or 7 thousand miles on it.I was told that these summit carbs use 'Holley' parts.Is this true? And i also would like to jet down a hair if i could.
