got my a14 with twin 45mm webers tuned on sat by jts
ever since it has been sounding like there is a miss in it but only when the revs are low and only under load
when it is just sitting there it idles perfect and revs fine
it has new leads/plugs/fuel pump/fuel filter/rotor button/dizzy cap/coil
cold this be a point and condensor problem as thats all i havent replaced or does it sound like a fuel prob???
or could it just be that the cam is #### driveability down low???
thanks

When u say miss, its not like a little back fire in the intake mainifold is it??? cause mine does that and ive heard a few other twin weber a engines do the same thing and i dont know wat causes it but its really annoying

yeah there is a little popping but not all the time
also forgot to say jeff rechecked the timing and its perfect so its not that either

anyone????

You say Jeff rechecked the timing.
Does this mean Jeff has seen it with the problem? Whats his diagnosis?
For the cost of points and condensor, Im suprised you havent already just changed them anyway.
If all else is good, I would be looking at play in distributor and checking that the carbon centre pin in the dizzy cap is not broken.

ur valves probly nead reseatting if u thing its missing not building up sufictiant compression coz the valves leak

the motor was rebuilt by jeff using all brand new parts
got a condensor and points today and will throw them in tomorrow and see what happens
when it was at jeffs i didnt drive it it just sat still and he tuned it as its currently unregod

Just out of shear curiosity, hows the 1200 coming along phunk? I remember was coming together well last photos...

sorry bout the hijack shaun

Id be asking jeff to have another look at it free of charge if ya ask me!

I would be sorting out rego and then giving Jeff the oportunity to drive it so he can diagnose it.


Datsuns all gone.
