hi i checked the pump and fuel levels and all are fine im going to reset the mixture to 2 turns out and idle to just 1 turn from contact on throttle and try again to tune it and see how it goes!

Thanks!

ball bearing at bottom of accel pump not sticking is it, or the needle sticking?

Hi,
I have exactly the same problem with my A12, but got a little familiar with the hesitation, sometimes i get the idea that the petrol you get these days isn't what it's supposed to be.
I also run my ignition timing more advanced than what the manual says +/- 15deg.

hi,
yer it revs very clean and nice in nuetral but in drive off idle it like dies and pick up then revs normal somtimes it dosnt fully dies just sputters!

and yes it points dizzy set at dwell 48!

Thanks!

Do you mean by "hesitation off idle" that when in neutral, idling and you jab the gas pedal, it dies for a split second, then revs out?
Or, when you jab the gas pedal, it splutters, then revs out?

U still got points dizzy?

there should be no hesitation anywhere. A is a very smooth engine

ohh sorry guys i meant to say $95 hour on dyno and $70 tune without dyno which i have already got done but didnt help the hesitation problems!

so one question is most people out thier driving thier datsuns with no hesitation at all off idle? i came to think it was a stock hitachi thing ?

Thanks!

$70 is cheap labour for anything these days. And most timing lights should be adjustable so can measure timing when it advances/retards.

I took it to 2 mechanics and they were lost aswell they hooked up a fuel mixture gauge in the exhaust and played with timing and fuel mixture and the hesitation still is thier!

Sikyne did offer for a dyno tune but he lives preety far away from me and I havn't got the time at the moment due to coming up vce exams!

i might have to end up taking it to a tuner!

anyone you know close to dandenong that is good at tuning carburettors and this kind of stuff?

Thanks!

By the way $70.00 is really good I think, you should seriously consider that, $210.00 to solve your, 3-4 month long problem is a good deal I reckon.

Last time I inquired to get my car tuned it was $350.00 from the word go, then there was a charge for every hour after the first. All jetting and associated costs were also charged to me.
