Hi
Does anyone know where the vacuum takeoffs are to balance the carbs as i cannot find them nowhere?, i have also heard that some dont have them, how
would i balance them if this was the case?

They are on the block below the rubber sleeves that hold the carbs on. On my C1 engine I think it ws the outer 2 that had nipples on and where linked
by some pipe and the middle 2 just have a 10mm headed bolt blocking the hole.

The problem is that now they are on a zetec manifold so i dont have them, if i disconected the map vacuum tubes on the manifold and connected the carb
balancer running the engine without the meagajolt on the edis, would this work?

Something like this may help?
Assuming the timing is already correctly set start off by setting the idle screws all the same 2 ½ -3 turns out, then balance the carbs when it is
running either with a flow meter or listening to the sound of the suck with a bit of rubber hose. One of the carbs is the master, probably the one
with the cable connected so get the next carb in the line sucking the same amount by adjusting the throttle linkage screws, then the next and so on.
You will have to adjust the idle speed as you do this as the revs will be going up and down. This will give you a good starting point, if there is a
lot of spitting back through the carbs at idle and slight throttle opening or overrun then the idle mixture needs richening. If the exhaust is sooty
after normal driving then perhaps the needles could be lowered to lean the mixture if it is sooty after a real thrashing then the mains are probably
too big. Conversely if the exhaust is very pale and it struggles under load then the needles need raising and possibly bigger mains, but without a
rolling road session it will be just trial and error, do runs then check plug colours to get an idea of what is going on.
