Hello!
My old polo II recently started having some problems. When i turn the engine on, it starts fairly easily, but the revs suddenly falls, and then the engine is impossible to start again. Only two things can start it:
1. Remove the air-filter cover at put some petrol directly into the carb. This method dosent work any longer. It will start with the petrol injection, but it cuts out again after 10 secs.
2. Remove the air filter and place a hand on the carb. air intake. When somebody turns the key, you feel a suction on the palm of your hand, then i remove it quickly and the car starts...usually takes 2-3 tries.
If the car has been runing within the last 8 hours, it starts without any problems.
Im wondering...whats the problem, and what should be replaced?
What model carburettor is in the car?
thanks

It's probably the automatic choke not working. A carb rebuild cured mine, but unfortunately brought to light a whole raft of other issues. Not sure where you would get a carburettor rebuilt these days, mind you.

Sseem to recall a lot of these back then suffering from unmetered air sneaking in via faulty carb to inlet isolation mountings.Rubber/neoprene blocks that perished with age,Something yours appears to have a lot of.

>Rubber/neoprene blocks that perished with age>
Exactly what happened to my son's Polo of the same age. Easily fixed.

There is a long history of discussion about these carbs on this site. Suggest you do a forum search, try polo carb pierburg etc as search terms
A good starting point
