View Full Version : Little help recognising things

Hi all,
Basically I've recently bought myself a little run about, but I've had to put a bit of work in to it already. Unfortunately I've come to a point where I'm slightly stumped.
Basically, I need help recognising the engine I have, and a couple of sensors.
The engine was changed by the previous owner from a 1.2 to a 1.4 that he removed from his race car. The block says its a C14SE, but I thought these were injection engines, whereas this has a carb on the top..

Also, it seems to be struggling to start unless the choke is on fully open, and if the choke is closed the car will cut out.. From this I also get plumes of white smoke from the exhaust that just smell of fuel.
I've done a bit of research and it seems to be a coolant temperature sensor that could be at fault. This brings me on to the next thing to be recognised. I have a sensor on the side of the engine (which is not plugged in to anything) , and also have one on the side of the radiator.. Which is which?

It will be the 1.4se single point injection not the multipoint as found in the mk2 nova Sri. I would swap the cts sensor.

Which sensor would I be replacing.. The one on the block or the one on the radiator?
Although, the one on the block isn't plugged in.. Could that be my issue?

Plug it in and see what happens. The cts sensor is a cold start sensor.
Looks like an SPI engine, but you say it has a choke... very odd, also there is a facet pump on the bulkhead, which leads me to think its a carb setup.
The bottom end is from the proper injection version though.
The sensor on the Rad is just the fan switch, its not any use to the enginer running.
If its a purely carb engine then the coolant temperature sensors is useless, you need to get it to a rolling road and have the fuel and ign setup
Yeah, I'm not sure what he's done, but the block definitely says C14SE, so I'm confused..
The problem with plugging in the sensor on the block is that there is no loose wiring to plug in to it.. That's why I thought the one on the radiator might be the coolant temperature sensor.
But from what has been said it could possibly have nothing to do with the problem I'm having. The fact it will only run with the choke fully open and as soon as I close it the engine will cut out..

Looks like it has been an spi motor but someone has had chew with the wiring or somthing so they have fitted a carb with the spi tophat modified to fit . Hence the reason its got the facet pump . As there is no mechanical pump on the cam housing ??
Sounds like it's multiple engines fused together! lol
So would could possibly be the factors behind my plumes of smoke, smell of fuel, and only running with the choke open?
Wrong carb setup and/or bad ign timing
Ah wonderful. How do I go about getting that sorted? Is it gonna cost me a fortune?

First of all take the intake plastic top hat off look in the center of the carb you will see a brass jet unscrew this out with a flat screw driver make sure its not blocked with water or white fuzzy shit . 9 times out of 10this jet causes a problem . Failing that fire the car up and why its running spray wd40 all around the inlet manifold gaskets see if the revs change could be a leaking gasket hence why it only runs on full choke . Then remove the dizzy cap and make sure the rotor arm is good and not burnt on the contact . And check the inside of the cap . These motors are very basic and not realy alot that can go wrong so I wouldnt be to worryed. Check the vac pipes on the carb are not split .

This is a carb that I keep asa spare n u can see even from been sat the jet is covered in the white fuzzhttps://uploads.tapatalk-cdn.com/20171222/af9d9551e572ddc38bf64aca7d3d599d.jpghttps://uploads.tapatalk-cdn.com/20171222/ca83c642d7e4d89625da85ad82f8aec5.jpghttps://uploads.tapatalk-cdn.com/20171222/717d6d1d2599ddbe801478c10bea64da.jpg

Is it a 2e3 or 1b1 carb on It?
Thanks for the help, I'll check all those bits tonight.
Couldn't tell you the type of carb.. How would I know?

Says in front of the pierburg stamp I think

If it's a 1b1 I have a spare. Doubt it though lol.

Well I've had a look at everything at everything and all seems good. The brass injectors look clean, the dizzy and rotor are almost new, I've just serviced it with new plugs and what not..
There is no free cable floating around for the sensor on the block, so I have no idea what's going on there..
Any other sort of ideas I can try.. Can't figure out why it would be over fuelling..
My carb has a stamp in front of pierburg that says 1B if that helps..

Yep that's what is used on the 1.2. I have a spare.
Sounds like it needs setting up to run a 1.4... was it running when the guy who sold it had it?
There is nothing to plug into that sensor because it's not needed with the carb and dizzy
Yeah, it was running.. It wasn't great but it seems to have gotten worse since I've had it.
Looking at the carb, everything looks good as new, so maybe you're right in saying it's not quite set properly..
I also forgot to try the wd40 on the inlet, so I've just been and given that a test.. It got ever so slightly better, but nothing major..
So on things I've tested tonight, I'm guessing there is a couple of contributing factors to my running problems.
