Carb Overhaul Kits

[Tony Smith]

The original Economiser or Power valve used in the Holley 94 Carb opened at 7.5in Hg vacuum. These Power valves are identical to the current valves used in modern Holley Carbs (eg Holley 650, 750 Quad carbs, etc) and are available nowadays in a variety of vacuum ratings, or even as a blank-off valve that doesn't open. They come in 2.5in Hg to 10.5in, and going to a 5.5 or 6.5 is handy to eliminate valve recession and burnt valves with modern unleaded fuels, but fuel economy will suffer, and if you should be running twin carbs on your Ford then going to 4.5 will be necessary to get them to open at all!

BTW, if you should also need Main Jets for your Holley 94, these are also identical to the Modern Holleys (and therefore readily available), and are a .051 size as standard.

Had to order the carb overhaul kit from Macs autos in the States still need a oil filter and head gaskets dont know if i can source in the UK as yet. Did manage to find a NOS contact set on ebay tho, and have got a quote to refurb the waterpumps.

Hi Alan
Are you talking 21 stud engine block AKA pilot/ uk built engine
Or
Mercury 24 stud.
If 21 stud head gaskets come up on Ebay fairly often and not over expensive.

Hi Steve / Tony thanks for the input pretty sure mine is 24 stud out of a carrier with cast iron pistons in i believe, but i will keep a eye on ebay. To be fair the postage from Macs in the USA wasn't as bad as i thought it might be but so far i only ordered a carb and fuel pump kit. Dont suppose anyone knows a UK part No for the Fanbelts ?
