AWEFULL in the mornings!

[datto_240z]

Well now i have the car running right... its a absolute swine in the mornings, or if its been sitting whilst at work etc.

It cranks/fires etc fine it just cant stay idling, even at full choke! I have to pump the throttle a little to keep it alive and eventually it will stay idling, just, at full choke. then when you goto take off it will die... almost stall but by pumping the thottle it will kick back up. When warm its fine. gradually gets better as it warms up

Could it all be due to cold start vac lines removed. there were never any coolant lines to inlet manifold. If so why do all the guys using aftermarket filters not have this problem?

What is it?

The car:

6/75 260Z 2+2 AUS model

stock evertything

New iginition system(everything)

Freshly rebuilt flat tops(well cleaned)

Timing at about 20btdc at idle, it doesnt ping at all and wont run at anything lower.

Some vac lines for emmisions etc removed

Thanks!!!

Sounds to me like your choke cables are not closing the butterflies on the carbs like they should...

usually when im setting my choke back up I make sure the linkage (on the sides of the carbs) is all the way in the down/off position, and then make sure the choke lever is fully down/closed...PRIOR to connecting the choke cables to the linkage..then connect them, making sure I dont move the linkage when attaching them.

then check the play when pulling the choke lever from inside, and ALSO checking to make sure the choke Is completely disengaged when I push the lever "closed" or off..

when you pull the choke lever it should bring the rpms up...WAY up if all the way engaged..so be careful
