New carby - what should I pay
The wifes 68 Beetle was running rough so I decided to tune it. Was running OK then I filled it up at the servo with 98. The next day or so it started
to back fire while driving. Had another go at tuning it and could not improve it. It was there and then that I decided there and then that was it with
my tinkering. I don't like it and it don't like me so off to the mechanic.
He tuned it, replaced the plugs and points, adjusted the tappits, etc and it was running fine. He mentioned that the carby was on its way out so he
compensated for that.
Drove it a few days later and it is running rough again. Slight back fire on the start up and then feels like it is straining. 4th gear the car was
shuddering a bit.
So besides all the tail of woe, what price should a new carby cost? I saw one on ebay for $318 and he rang a supplier and he quoted $400. Any tips on
where I can get one for a good price?
Does the above sound like a carby???
Cheers,
John

No he has not pulled apart the carby. His opinion is that to stuff about with it would cost nearly as much as a new one....

Between the Idle jet and main jet, there are so many problems that can be fixed by taking them out and giving them a blow out and cleaning them.
If you are handy with tools, or know someone who likes to tinker, take your carby around to their place with a six pack, and sit down together, chat,
disassemble, clean, fit a minor rebuild kit (gaskets and seals), and take note of how many turns in and out all adjustments were, and put it back
together.
Can be quite good fun, and also enlightening. 
Have a look here. Have a read and see if it will work for you.

JohnL, Before you change the carb., or send it away for a rebuild, check the other (simple) things in the fuel system that could cause lean runnng, or
periodic fuel starvation.
eg 1. Blocked fuel filter. (or possibly outlet from tank).
eg 2. Failing fuel pump.
eg 3. Water or dirt in fuel tank/lines.

Back firing sounds like it may be misfiring... spark plug leads or distributor cap...
OR
carburetor flooding....??
Many people these days Prefer to have their GERMAN SOLEX carburetor overhauled that buy a new Non Solex carburetor..

Thanks to all for all of your advice. The situation is the carby has been replaced but the problem still exists (so I have been told). Now let me say
that the mechanic was recommended to me so I do not think he is taking me for a ride. He spent his apprenticeship working on VW's so he was very
excited when we took it down to him.
I did check out the vollks.com.au site Lee and it is awesome. They have a lot of good stuff. The carby is not in stock and won't be for another 30
days (I emailed them yesterday morning).
So the thing I am thinking is the fuel....
hellbus - thanks for the tip. I do have a mate that loves tinkering with cars but I hate to impose on the guy (any further) as he is busy enough as it
is. It is just something I do not seem to have the patience for. Need to leave it to the experts. I had the shits when I could not fix it the other
weekend something bad.
Will let you know the final solution.....

If it's not a fuel problem, it might be worth replacing the condensor and coil. Both can appear to be working, but then play up and cause variable
rough running. Even if the new parts don't fix the problem, it adds to your spare parts collection...!

When does it backfire? Foot to the floor or cruising steady? My beetle was backfiring whenever i would put my foot down and gave it some, and also in
4th gear. I chased the problem around for a day or two, checking fuel, carb, points leads, etc. Turns out the coil was on the way out and was causing
the backfiring. Check your coil or borrow one and replace it to see if that's the problem.

Spoke to the mechanic again today and he fitted a refurbed carby from the dude in Gosford. He says it goes OK for a while and then starts to run rough
again after driving it for a short time. He used the old carby and the new one and changed parts around so no joy. I might mention to him about the
condenser and coil as I do not think that he has tried that.
As for the backfiring it happened when I was turning the engine over. Not real loud but there. Also when accelerating. Not putting my foot to the
floor or anything just trying to drive it normally...
ANYWAYS - the question I have now is since vollks.com.au do not have any carbys in stock, does anyone have a plan B I can initiate?

I would say Coil. I have had problems like this before. Condensor and points is cheap and an easy way to rule them out of the equation.
I would also cheak your leads......are they routed well? Not such a big issue in a full tinware bug but i one had a lead that had melted on my
extractors in the baja. just slightly but it was enough that it wouldnt rev nicely.
Your mech would have a coil lying around to try.

Mechanic has informed me that he has replaced the coil and the condenser. He is convinced it is the carby......it has a 34pict on it. He thinks it
might be the wrong carby on it. Says there is a slight delay in first and second. WhenIi bought the car the bloke told me it was a 1500 bored
out to a 1600. Mechanic is going to try a different sized carby......
What a drama. I am going to be up for $7,000,000 dollars at the end of this....
I have had feeback that the new ones are from China and are crap.
Cheers,
John

Some more ideas...
a. Rotor button? They can go intermittent, if they have a 5kOhm resistor in them (as almost all do). Easy to change.
b. Also the spark plug connectors (brown 1kOhm resistor type) should be swapped for another set, assuming you have the original Cu-leads (or replace
the leads entirely if they are the modern sort). (Original black plug connectors should be OK; check the attach to plugs tightly as the little
spring-connectors can break.)
c. Is the vac advance working? If the diaphragm has failed, the engine will run with less oomph, and may run lean, & backfire intermittently.

Thanks for all the help but hopefully it is sorted. I hear ya Craig but seriously I hear all the time about people that are probably as knowlegable as
a mechanic having to replace this and that before they get to the heart of the issue.
Ended up costing about $800 and mechanic told me that when the engine was modified, it was not done too well. I do trust the guy although I have only
used him a couple of times. The stress of having to pay the money though is far better than the stress if I had to do it.....
Question, in the carby, the butterfly flap (not sure if that is what you call it - the round bit that opens and closes on acceleration) has a hole in
it but this was soldered up. Why would that be?

Well the dude went right over the car and replaced a heap of stuff that looked or was dodgy. I have had the car for about 3 years now and in that time
have only replaced the plugs and points as far as the engine goes. How long anthing else was done I do not know. So here is what was changed:
Carby
Inlet Manifold gaskets
Pre Heat Pipe Gaskets
Filed the manifolds flat
Replaced the leads
Replaced the distributor cap
Replaced the rotor
Replaced condensor
Replaced points
Changed the fuel
Replace coil
Fuel filter
The car is going the best it ever has....

Just checked a few of the carbs I have here, they all have a hole in the accelerator butterfly, about 2mm diam.
