my first car* 1.4 1990 340 Carburettor Help Please!

[valman]

cheers vnd!

need a little bit of help guys - i took the carb off to clean it up a bit but that was last week, now im re-fitting it and theres a thin hose that goes to one of the little pipes next to the idle adjust screw. does anyone know where this pipe connects to? and what its for? will the car start without this fitted?
cheers

if its a B14 on the left (facing the front of the car) I think its a loose breather.

yep it goes from the renix unit, like a vacuum hose or something. worst comes to worst ill just try it on each one untill it starts lol

From the renix unit should go on the mostest manifold side, i.e. at the very base of the carb, it's to measure manifold pressure.

That was my second guess.
I hate it when people butt in with facts.

But your correctness percentage is at an all time high recently dude!

I know. But correctness butters no parsnips. I'm pumping up the guesses as my post count is feverishly close to yours and I'm pushing hard for the silver medal position.

cheers chris! do you happen to know what the other 2 vacuum holes are for? as i've got no clue without my haynes manual being here, keep forgetting to bring it to college , theres also another hose that should go towards a throttle adjuster valve? (i think thats what the technician said it was, cant remember its like a bit thats on the carb that is furthest from the engine and has a diaphragm in it. i should really get pics and highlight the bits i mean shouldn.t i? haha

[valman]

well the sills are done! unfortunately the pictures i have of the "progress" are totally wank to put it nicely. but i was pretty chuffed with the work anyway. i just went out now in the dark and got pics of the final product and pretty pleased with it. i cba'd to grind the welds off as i was running out of time. plus this isnt a show car, just a drift slag in progress
here are ze pictures:

this was the best picture i managed to get of the progress i think i should get a proper camera. but you can see here that the welds are good n strong
the hilarity of realising after putting on two inner sections that the welder was turned up to 5 instead of 2 (has a weird dial on it that has 2 pointy bits either end) and struggling to not burn holes was good though!
finished product:


the technician did the blanking plate for me as i think he wanted a go with the welder pretty good bodge if you ask me; cut, tack hammer, tack hammer, tack until it all fit - cheers owain!

this was the underneath section, i did a stupid thing and made the panel point flat along the car so it was really difficult to weld. if youre going to do this, make sure the outer section sits on top of the inner so you have a vertical surface to weld on, instead of welding upside down.

all that havoc above is because there was a 10mm hole where i didnt bother spending loads of time to make everything fit perfectly, so it jsut got filled with weld instead. as apparently its an mot fail if left as is

again gaps to bridge etc made this look quite messy at the bottom. but the tidy bit was there as the panel was flush and was easy to weld haha
so i am one step closer to having an MOT on this, criticism welcome!!

more to come soon!

[valman]

oh and i got to test out the engine mounts too!! bloody epic! engine only slightly rattles now and the vibrations through the car are hardly noticeable

[valman]

right, here are the pictures that i got to see if you guys can help me sort out the carburettor/ dieseling issue. i hope you wonderful bunch can help v : the first one shows the connection that has nothing going to it: (one closest to bottom of picture)

and here are the other 3 - what should connect to these? as you can see i have the hose that goes from the renix already connected to one like Chris_C said. but i have no idea what shoul attach to the other ones


thanks all

that;s the wrong carb for that engine mate. that's a 32 DIR 110 judging by the pics, should be on a B14.4S and not on a B14.4E

on a B14.4S the pipe to the right of the mixture screw, is for the Exhaust Gas Recirculation valve
and the pipe above the renix's vacuumconnection is for that other thing that's not connected at the below side on the above pic. that's the decelleration mechanism.

i'd block both these ports, cut 2 pieces of vacuumhose and block them with a bolt or sth similar, don't connect them 2 with a single hose as this affects the carb.


renix's connection isn't directly manifold pressure. at idle, the port is closed. only when the throttle is slightly opened the port becomes free

Cool work man, good weldings also

[Nimminz]

nice 1 on the welding! i'll be doing a bit of that soon fingers crossed

thanks for the info mate, do you know if it will still run ok if i block the ports off?

cheers for the comments on welding! its getting there, might need to swap the front suspension out for the MOT though - there is NO travel in the front atall and i believe thats an insta fail haha

[tim-andre]

nice, like its lowernes
how are the landys to drive with on normal bumpy roads btw?
