Spirex Carburetor on Mk2 2.1l 8v golf

venusion · Post by **venusion** » Thu Nov 17, 2011 4:00 pm

Hi there, is there anyone with a bit of knoldge of a spirex carb sold by Goeie hoop onderdele and Autozone fitted on a mk2 golf?

I am having problems finding where which vacuum line needs to be connected. I also think someting got stuck in my carb as my my car will not start.

Heres what happens:

When i pour fuel directly into the carb the car starts and runs for a few seconds but dies after that even if i floor the petrol pedal from inside the car or on the carb itself it just dies.

This is the only way I can get the car to start.

I have done the following:

Replaced: Ignition Coil, TCI-H unit, new spark plug, new HT leads, New battery, new fuel filter, checked all the fuses and relays.

I have an electronic fuel pump in the engine bay that supplies the carb with fuel. I have unplugged the fuel line from the carb to the pump and turned the ignition and managed to fill half a coke bottle with fuel. So to me that says the pump is also working.

The car has been standing for a bit longer than 8months and would really like to get her going.

Will appreciate any help!!!

is your needle and seed on the float open ?have you tried blowing into the petrol pipe of the carb ?

Have blown through the fule pipe between the carb and pump and nothing is stuck there.

Its a new carb that was fitted and the car only ran for 3weeks before we we stored the car in our garage after moving. Havent had the time to drive the car in 8months.

The problem is that the carb does not look the same as the normal pierburg, solex, or weber carbs. I need to find a diagram or more info on how to work on this carb. The guy that fitted the carb did not even know how it worked.

Firstly welcome to the form. Are you sure you have the petrol pipes on in the correct way around?

venusion · Post by **venusion** » Thu Nov 17, 2011 4:46 pm

Pipes are connected the right way round.

venusion · Post by **venusion** » Thu Nov 17, 2011 4:50 pm

pipes are connected the same way it was when the car was still running. Have also tested the fuel pump and fuel came out of the pipe and half filled a coke bottle.

was gonna say that, i'v had mates struggle for hours only to discover the pipe from the pump is on the wrong pipe on the carb... sounds like needle and seat are jammed. if u look into the carb and open the throttle with ur hand does a bit of juice spray out?

No fuel seems to be getting into the carb. Have tried your suggestion Mashall. Cannot see or feel any fuel.

show us a pic of the carb and where the fuel line connects to it? is there a big screw kind of in that area? the float adjustment screw. try finding all the adjustment screws. then turn them all close and then turn open a few turns...that should at least help make sure it starts..then just adjust to get even idle...

Took some photos of the carb and fuel pump.

you don't have one of those stupid fuel cutoffs for the vesa level4 immobiliser in the line somewhere. Had a car the totally f-ed me around for hours only to find 2 of those bastardly things in the line and the one had died.

venusion · Post by **venusion** » Thu Nov 17, 2011 5:28 pm

Luckily not. No connections between the fuel pump and the carburetor. Straight forward pipe from fuel pump to carburetor.

Seen now on the side of the carb it says KYAN. So take it this means it is not a Spirex. Can also not find any screws except for one flat large one on the side but this has a washer/gasket on it and was completely closed.

is fuel coming out the pipe at where it clamps unto the carb?
The float level adjust screw is under that white plastic cap where the fuel pipe clamps unto the carb.
Could be sucking air from the base plate as well but should atleast start or try to take

venusion · Post by **venusion** » Thu Nov 17, 2011 8:38 pm

Hi thx for all the replies!!! Very much appreciated.

Fuel is coming out of the pipe that clamps onto the carb. I have removed the carb now and fuel did come out of the carb. Just think it is not getting to where it needs to go.

Do I just remove the white plastic cap and then adjust the float?

When I removed the carb I also found that there is another screw at the back of the carb is the the "air mixture" screw?

Thanks for all the help I am so frustrated with this carb that I am thinking of converting to sidies

have you grounded your carb from the carb itself to the one of the head bolts?

venusion · Post by **venusion** » Thu Nov 17, 2011 8:53 pm

The carb receives power from the ignition coil and is grounded on one of the head bolts.

dirty d · Post by **dirty d** » Thu Nov 17, 2011 9:03 pm

looking at your pics. where is the vacuum pipe of the dizzy? if i'm correct, that pipe needs to be connected to vacuum inlet above your choke and accelerator cable? my carb golf is in the workshop, so i cannot 100% confirm my finding. i have another carb here and that vacuum thingy operates the small butterfly of the carb. have a look dude

jetta786 · Post by **jetta786** » Thu Nov 17, 2011 9:06 pm

it is a kehein carb supplied by spirex. the power to the carb from the coil is to control your idle switch/valve. this wire runs to the back of your carb. somehow your vacum pipes dont seem to be connected correctly. disconnect all the vacum pipes on the carb. if that does not work then open the top of the carb and check the float and needle/seed. in order to remove the carb, you require to undo the 4 10mm bolts.

venusion · Post by **venusion** » Thu Nov 17, 2011 9:11 pm

Thanks Jetta786. Ive got the carb out do you perhaps know which vacuum pipe should go where on the carb? There were two them blanked of. The one behind the carb below the idle switch and the one in the front below the Ground wire.

dirty d · Post by **dirty d** » Thu Nov 17, 2011 9:12 pm

by the way how is your fuel pump doing? my mechanic is taking off mine due to it running out of steam in 3rd gear when i drive it hard. those pumps pump at one pulse and doesn't increase the pulse once you high in rpm. mechanical pump is being fitted as well as an intermediate shaft that runs the petrol pump and oil pump. a blank off plate also needs to be made. thought you might need that info

venusion · Post by **venusion** » Thu Nov 17, 2011 9:15 pm

Thx Dirty

I havent had any probs as the car runs on avgas and likes the higher revs runs fine even in 5th gear. But its always good to see what can be improved.

jetta786 · Post by **jetta786** » Thu Nov 17, 2011 9:41 pm

the vacum from the dizzy can be connected at the back below the idling valve.trying to picture the front of how my carb is set up, but for the life of me cannot remeber, nevertheless take of the vacum hose in the front, i cant see from your pics where it is running to. if your float/needle and seat is all ok, then the car should start. put the carb back and choke by placing your hand on the top of the carb and let someone start while doing that. lift your hand up and down while you give it some throttle.i.e open/close choke.

venusion · Post by **venusion** » Thu Nov 17, 2011 9:49 pm

Thx for the help jetta. I am cuurently busy taking the top off of the carb to see of the float and everything else is ok. Will put the carb back in the car tomorrow morning and try your method.
