vacuum valve type thing
Ok. I admit defeat.
I've been trying to figure out now for well over a month where the vacuum pipes in the picture should run to. i took them off thinking i'd
remember where they would go to, but..................................................................8 months on, can i remember where they go, can i
buggery it's off a '90 1.6 carb pinto btw
the engine starts, ticks over (albeit a bit lumpy) and runs without a problem, but i assume they will be needed for some sort of economy and
definitely for vacuum advance on the dizzy.
I assume that one of the pipes is a vacuum feed and then the vacuum is switched due to coolant temp (the green bit has a copper cylinder on
t'other end that sits in the manifold water jacket) i've half decided on what should go to the dizzy, but that's about it.
Therefore has anyone got a complete 1.6 pinto with this system still intact?
can you tell me where the pipes should go based on coloured stripe/ position from green bit?
also what comes off that bare t? wher does it go to?
as you may notice, i'm completely flummoxed (is that a word?) and would greatly appreciate any info, pics if i can be cheeky enough to get you to
brave this wind to the garage.
Go on do a lad a favour on his birthday (20 mins into it now)
cheers
Tom

I had the same problem with the 'Ported Vacuum Switch'
http://www.locostbuilders.co.uk/viewthread.php?tid=14722
In the end I decided to ditch the whole thing. I've fitted a blanking plug to the threaded hole where the switch was (I have a spare if you
need one) and taken the vacuum feed for the dizzy from the port on the side of my weber 32/36 DGV carb. I have to point out I haven't run the
engine yet, but I believe it whould be good to go.

The one with the round plastic thing (spark advance valve?) goes to your distributor but I see it has a 'T' piece on it, put a piece of
tube on it and block it with a screw, it's weakening your mixture which is why you are running lumpy.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I cut all my pipes short and pluged them with M6 bolts.
Except the one from the cylinder head side of carb which is used for vacum.

im running my 1.6 with no vacuum pipes, the distributor just has a hole, the airbox i replaced with a small K+N, the one to the servo i cut the nut
off the cable, welded it shut, and screwed it back on. engine runs fine, but it does stall when hot at times, and then not want to start...

Classic rich mixture syptoms?
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

it could well be, mark. i was planning on posting on it one day, but never got round to it. I always suspected that it was due to the absence of a
fuel return pipe, too much being forced into the engine. the exhaust is also quite black, so i suspect you are correct.
but how do i correct it? more air or less fuel i guess, or maybe a nitrous kit... are there any simple steps to reduce the mixture? really, it
should be leaner than before due to the less restrictive air box.

Adjusting the mixture screw would the first place to start, if this does not get it within limits, check the air filter is clean, there are no
obstructions etc, check the choke is not holding on
