I have 2 sets of carburetors I am mostly concerned with the main bodies not the throttle body or the air horn One set is stamped O-1158 & the other is stamped 0-153 They look basically the same on the inside Are they interchangeable ? The one thing that is different is that the 0-153 have a hole drilled in the bowl area on the front ride side between Right Idle tube well & the hole the vacuumeter piston goes in The hole is drilled all the way into the semi-circle opening below the accelerator pump nozzles while the 0-1158 doesn't have this hole there is a small indentation where you would start to drill Also the nozzles them self are different the 0-153 has 2 small holes on the bottom aligned with the semi-circle opening in the body & the nozzles are shorter but a bigger opening The nozzles on the 0-1158 have 2 holes in the center hole where the screw with the holes in it for the fuel to go through Any Carburetor experts out there I would appreciate any input Thanks Larry Jabin [Non-text portions of this message have been removed] ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to http://autos.groups.yahoo.com/group/Chrysler300/join and select the "Leave Group" button For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylangYahoo!
