Hi my 2 litre Aircooled is a nitemare to start in the morning or when its cold, keeps cutting out and i have to rev it to keep ticking over. Dont know what its like when its warm as only had it 3 weeks, iv serviced it new leads plugs etc. Does it have an automatic choke?. once started it runs fine. Is it just this shat weather were having, constantly pissin it down here one minute then completly frozen the next (Manchester)

The temp or weather should not bother an engine, if it does not run properly when it's cold then the choke mechanism is faulty...simple

Silly Question Or Not?
When you start the Aircooled buses.
Do you turn on the ignition and before turning the key to start , deploy your accelerator foot to the floor to set the cold start like on the Beetle?

Good point, I assumed an Aircooled or VW owner already has this information

Correct....one single depression of pedal.
Do you get fast idle?

You have an automatic choke and the guys have explained how you set it. However, If the wire connecting the choke is broken then it doesn't set and you are trying to start your engine without it. Check the lead. Also, there is a fuel cut off valve which is earthed to the engine block. If that is broken it will also cause serious problems. Good luck.

Ok thanks for the info will check tomo.

If the wire connecting the choke is broken then it doesn't set and you are trying to start your engine without it. Check the lead.

Are you sure about that? The 12v feed to the choke heats up the bi-metallic strip and that gradually opens the choke flap. If there was no feed the choke flap would stay shut wouldn't it?

Yep it would stay shut and over choke the engine as it warms up.

Had a look at me flaps today and they are closed when engine cold. Checked all the wires pulled them off cleaned etc, I turned the ignition to on and depressed the pedal twice, waited 20 seconds or so and turned the van over. BANG it started straight away and idled fast, no problems. 40 mins later went to go out in the van and it would not start for about 5 mins, felt as if no fuel getting in, eventually started and drove fine. After that started no problem as it was quite warm. Did notice a little oil in my airbox lid and also oil spray from exhaust, is this a case of too much oil in engine, Filled it to inbetween min and max the other day when i serviced it?? Faggie said he would have a look at it for me and he also says to disconnect the choke, would this make it run lumpy still in the cold startup??

Don't disconnect the choke, If they are not working properly set them so they do. The choke flaps should be fully open after 3-4 minutes (closer to 4 minutes this time of year) of engine running from a cold start. The oil from the exhaust is more likely a mixture of sooty condensation and unburnt fuel when on choke, a small amount is normal for an engine with a carburettor.

Thanks for that was getting a bit worried then after spending 4 grand just before crimbo. I will do a test tomo to see how long they take to open. Do i just leave it on tick over to see how long they open, its just sometimes i have to blip the throttle to keep the engine from cutting out. If they are taking longer to open up how do i alter this and is this also a cause of using shed loads of fuel. Sorry if im bein a bit slow but im very new to Aircooled and just gettin my head round it all. Hate breaking down so i like everything sweet. My missis has a mean look of dispair when anything goes wrong !!
