timing. hope anyone can help me.

camshaft timing?
ignition timing?
So you installed the 2.0 engine into the FOX?
Are you staying with the carb or going with the fuel injection?

I am staying with the carb. I had to set the timing faster so that it
could start. If the timing is set by a timing lite and you want to
start it, it is like the battery is flat.

OK
How is the ignition advancing?  Are there vacuum controls on the
distributor?

No there is no vacuum controls on the distributor. My old distributor
does not fit because the housing and gear is smaller than the polo
distributor. I cant find another distributor with vacuum cotrols that
does fit.
dave AKA vwdoc1 - 08 Jan 2009 12:52 GMT
Well that surely is a problem if the ignition timing can not advance or
retard!
Engine should run crappy!

How is the spark created?  From the distributor Hall Sensor or from the
CranKshaft position Sensor (Engine Speed Sensor)?
I will assume that you don't have a functioning Knock Sensor either!

I have sorted the timing problem. If the revs is at 5 & half thousand
the car starts to gerk. As soon as the car goes up a hill it starts to
gerk again. Is it the carburettor of  the 1.8l carburettor to small
for the 2.0l polo. Will it help if I put bigger main jets in to the
carburettor.
dave AKA vwdoc1 - 09 Feb 2009 22:32 GMT
It might be a fuel related problem now.
You did not mention how it runs with the ignition working well nor what you
did to fix it!
How did you sort out the distributor issues?

Maybe the engine is not receiving enough fuel due to that carb or the fuel
getting to the carb.
It almost sounds like a low fuel in the bowl condition.

Does this engine have an Oxygen Sensor and controls on the carb?
Does the exhaust have any restrictions in it?  Is it big enough for the 2.0
engine?
I think that VW, at least here in the USA, stuck in a restrictor right after
the catalytic converter to probably slow the VW Foxes down some!  They did
not want the Foxes to beat out the more expensive GTIs from the light!  lol
