running rich terrible efficiency -please jelp.

Hi There.
lately when i start my 70 bug up ,she blows out alot of fumes and smell alot of fuel.when i fuel up ,she has also been using alot more fuel than normal.I seem to think that the carby is running extremely rich.Would anyone be able to point me in the right directions as to how to reduce mixture on carb?


Thanks in advance.

Make sure the choke is getting power and isn't stuck and is fully open after about 5 mins of running.

If there's no power to the choke it will stay shut unless it's jammed open

thanks for the reply joel.
Nah mate chokes all good.Running fine like it should be.
not sure.im just sick of people getting fumed out when i take off,
bit embarrassing.😀 plus i fuel up on Monday,up to half a tank,,now its just Wednesday and i
have just under a 1/4 of a tank.SUKS..never used to be this bad.i had ago a while back at
tuning the air fuel mixture,so i think maybe a set it too rich.woops.

today!!! more trouble.severe back firing and missing.Left her at home today.
looks like i will be working on my car this weekend.🙁

be aware that when turning the small air fuel mixture screw (if its 34 pict)... its an air bypass screw. such that ccw (winding it out) doesn't actually make it rich, it leans it out! and cw (winding in) makes it richer.

Course not relevant if stock 1600 with 31 pict.

any chance of a pic of Your carby Jas

check out ; http://www.vw-resource.com/
and check out tuning Your carburetor...

also check for fuel leaks...

mixture is supposed to be done with the engine hot...

My beetle always smells of petrol around the engine when I park it in My carport
no leaks... and goes fine..

sorry no pics atm,need to upload to photobucket.
the carby is a brand new soloex 30/31 pict carb.

an old mate of mine,said to wind it all the way in and then screw it out 1 and a half turns.
not sure if this is correct?

That is a starting point - not a finish
