Nahuelcalli Posted June 17, 2019 Share Posted June 17, 2019 Hello, new z member here and first time owner of an s30. I have a stock 74 260z. My issue is that for the life of me i cant find a way to properly tune this thing. These are the Hitachi HBM46w carbs on the L26. Please dont comment telling me to ditch them for the earlier generation carbs. I have no desire to really spend money on carbs, i just want these to run some what properly till i do an rb swap. Any help would be greatly appreciated. Thank you Quote Link to comment Share on other sites More sharing options...
ZHoob2004 Posted June 17, 2019 Share Posted June 17, 2019 I might have just the thing for you. I came across this manual about a year ago in preparation to install these carbs on my L28 (I haven't got that far yet, but they're intended as a placeholder until I go standalone). You may find what you need in here. 1973 240z 1974 260z fuel system modifications.pdf Quote Link to comment Share on other sites More sharing options...
bunkhouse Posted June 17, 2019 Share Posted June 17, 2019 Try asking over at classiczcars.com. There are a few owners that know all about flat tops and love them. There's a good thread titled "We're bringin' back the Flat Tops". Quote Link to comment Share on other sites More sharing options...
