xa1973 Posted August 6, 2009 Posted August 6, 2009 What are some of the issues that your having.... Quote
DaveDimo Posted August 6, 2009 Author Posted August 6, 2009 i have just put a kit through the carbs they are in brand new condition and i just cant seem to get them running right and in sync with eachother there are all these adjustment screws and like three idle scres haha i really just need somone with years of datsun experience to tune it up but when i drive it it runs amazing like a brand new car just the idle mixture and the carb sync i think is the problem. i am going to replace my mechanical pump for an aftermarket solid state electric and up the psi to 4-6 and get the fuel preassure up there and consistant. my dad done the same years ago and he said it was a good thing he was running 6si pump on carb system with no worries and it helped with cold starts because the electric pump primed before start. so what that is fitted i want to take it to someone in the area with the nohow to tune it at idle the car is a one owner early 74 260z 2+2 i kitted the carbs and adjusted the bowls and choke to perfection the car has done 147,000 original Kms its an awsome car log books and all.

aussie240z Posted August 6, 2009 Posted August 6, 2009 Hi I am also in the area (Woonona) with a 240Z, triple 45mm webers etc as well buiilding a new engine at present. Fitted the webers and useed Fairy Meadow Carbies to do tune and dyno, very successful. PM me a contact and lets see what can be done Cheers Ian Quote
C.A.R. Posted August 6, 2009 Posted August 6, 2009 FFS Dave, your running the Flattop Hitachi's - even rebuilt they can't be tuned right! Ditch them for a set of 240Z SU's & never have trouble again. Oh wait - it "has to stay 100% original" doesn't it? Quote
(Locky) Posted August 6, 2009 Posted August 6, 2009 i bought my 240 of a guy that runs a workshop in the gong he has 3 of them and could probebly help forget the name though :-\ Quote
stevo_gj Posted August 7, 2009 Posted August 7, 2009 I recently went through a bit of an ordeal installing and tuning 240z carbys, but in the end the problem was being caused by loose tappets and once fixed the carbs ran bloody brilliantly. I second Lurch's suggestion of installing the round top SU carbys. I was able to use resources on the internet and a couple suggestions from fellow Zedders to get them tuned/synced nicely. Quote
DaveDimo Posted August 7, 2009 Author Posted August 7, 2009 yeh i know nick and i had a good chat with him we screwed around with it and the car seems to be holding idle rather good now and driving it is like a new motor so its so far so good. just need the carbs synced now and we should be good to do a final tune. any ideas how to sync carbs also i need a factory service manual for my car so i can tune her up. im possitive these carbs will work and i have faith that i will get them right. if not i have a 280zx efi system that is ready to bolt on but i really want to keep the old girl running as factory as possible.
