G'day dudes,

I have a 1500sp with a 30pict-somethingarather which i have in my 68 beetle at the moment and for some reason it running rich, so much so that when I screw the fuel mixture screw all the way to the lean side it still produces some black smoke on quick throttle blips. Could this be a sticking needle or something like that? Should I pull the carb apart and clean it or is there something simpler?
Any suggestions are much appreciated

What is a Mofo? STEP 1, check your timing is not retarded,
STEP 2 the screw you are turning is the Idle mixture only, if you screw it right in & the engine is still running it is getting fuel from somewhere else, take the aircleaner off & with the engine running & the choke flap open, look down the carburettor (you may have to use a mirror) , if you can see petrol dribbling down onto the throttle butterfly, that is your problem, simplest cause of this is flooding at the needle valve & seat in the float bowl, simplest cause of that is a little bit of dirt stuck there not allowing it to close fully, if you know what you are doing take it apart carefully & clean it, you may not see the bit that caused the problem, then- before you put the fuel line on, put the fuel line in a glass jar disconnect the high tension lead from the coil & crank the engine for a coupla seconds or a few times by hand to clear any dirt in the fuel line, then start it & see how you go REMEMBER one step at a time otherwise you will never know what you fixed. :alien

Cheers Kombikim, I'll give that a try and see what happens.
By the way mofo is an abbreviation for an obscenity, I think.

I am sure Rob (aka Aussie bug) will come here and tell you the truth.
Anyway i wil jump in to get my post #'s up

That is his site above - go there and look under tune ups and find your carb. Have a read of that and go from there

thats a really good website, I never really looked at it before. How do I get my posts up?
hope I haven't misled you jboy82, only telling you what I would start of with

One word for the website... nice:thumb
I checked the carb and I noticed the solenoid(? with a wire attached to it) was loose so I screwed it back in and the mixture adjustment screw works fine again(thats how loose it was).
Cheers Everyone.:party

Will have to go into the next KlubVW newsletter!
Kool site!

As I understand it a Mofo is shorthand for non-VW person.

Thanks for the nice words on the web site guys - much appreciated.

jboy82 - I had exactly the same problem with the 30pict/2 on my 68 the other day - it started chewing fuel and I KNEW it was in tune (had done a tuneup a few days before), then found the idle shut-off solenoid had worked loose.

You'd think it would make the engine run lean (air leaking through the threads) but no - super rich is what happens.

It's a fine brass thread in the soft metal of the carby so it can't be screwed in HARD and the weight of the solenoid tends to work it loose occasionally.
