Thread: carby over haul

Hey Mark,
the carbs on the green 2 door might solve your problems.

Pete

My experience is from a LOOONG time ago but it should still be the same.
The kit usually has everything but a new fuel needle and main jet.
These have to be bought separately.
You should perhaps check the diaphragms first. This entails only undoing 4 screws at the top and looking in.
Regards Philip A

Hi Mark,

I re-sealed my carbies a couple of years ago.
I cant remember if the kits came from repco or coventries but the kit comes with all seals a new diaphragm and i`m pretty sure it had instructions.
You will need two kits obviously and if i remember correctly they were only about 35bucks each

if you get a bit more power when you give it some choke it might be the dizzy back plate thats worn. I had dramas years ago in UK with a V8 lightweight. If you give it some choke it was like a turbo kicking in. The motor had Su`s and i tried about 3 sets with no difference then changed the dizzy and the problem was solved!

Ian

Thanks Ian.

It only needs the choke pulled out about a quarter of an inch and its not like extra power, i just stops the bloody thing from misfiring/fluttering. Its more like an intermittent and brief stall where theres a sudden loss of power for a split second and then it comes good very weird

check your manifold vac, dizzy vac advance and the points plate.

yep, they're all there

what should I be looking for specifically. We have already checked for vaccuum leaks (none found) but what should I look for on the points plate as mine has electronic ignition.

thanks in advance

Suck on the hose to the vacuum advance unit, to make sure the diaphram is OK
Make sure the advance plate is twisting OK (watch the plate move when sucking diaphram)
Wiggle the rotor button for play / Check for not worn
Take rotor button off / check shaft for play (wiggle it) // Watch, look at the air gap between the "star rotor" and the "pickup" (under the clear cap)
Lube the advance plate / Check spring tension (smooth, not stuck)
Check Dizzy cap for condition / burnt lobes / hair line cracks

Then .... Put a timing light on / check for any "variance" in timing mark position on the Harmonic balancer
