My Beetle 'John Lemon' is really starting to look the part. This weeks task was to do something about the terrible old interior. It is getting so close to being finished. I love it.

Glad to see you kept the original "horsehair" seat pads. Can't have Brazilian horses careering about the paddocks in these pc times :D

More due to that fact that I am too tight to replace what was there ;)

The next purist will thank you.
Reminds me of the Leunig cartoon with a punk couple levering off the boards of a tabletop.
"Wow , genuine 50s laminex - with silver flecks!"

Jeff, check the wire between your fuel sender and gauge for high(er) resistance (I assume the original wiring may be brittle etc), and alternatively bypass with a new wire to see if that improves your fuel gauge reading. Wouldn't hurt to double check earthing locations too. I, as electricity is lazy and will take the path of least resistance!

Cheers

Does your carby have a choke?

On my kombi, if I warm start, sometimes I need to reset the chokes. I believe pushing your foot flat to the floor should reset the choke.
The choke is also adjustable - when it's warmed up, it should be pointing straight up and down... when starting from cold, it should be 'just' closed.

Here's some good pages that I've used:
https://www.wikihow.com/Adjust-the-Automatic-Choke-on-an-Aircooled-Volkswagen-(VW)-Beetle

http://www.vw-resource.com/automatic_choke.html#adjust

Not sure if you've checked this already, but after you drive it and it's warmed up, if you open the petrol cap, is there any sound of air hissing?

If none of the above, I'm stumped.

I think I have worked out that it is the needle and seat in the carb is not sealing properly and the fuel is pushing past it. I will pull it apart next week and see if I can sort it.

Looks good Jeff, you just need to paint the underside of the engine lid (and put on some wider rims (no slots) with hub caps).

Haha, not for this one. If it had some power then absolutely, but wider wheels on the stock power plant is just a little bit of overkill :P 

Oh, and yes I do need to paint the underside of the engine lid ;)

I know naaaaaasing. ?

Is there an insulation block between the carby and it's mount.

Different application I know but the old stromberg had no block as std equipment and the fuel would get hot whilst sitting after a drive and was harder to ignite according to an old fella.

True?  I don't know, but I put one on it and it was much easier to start.

Sometimes us old fellas know more than the young fellas. ?

I think I have found the source of the problem. I am pretty sure (still need to confirm) that the needle and seat are not sealing properly. I will pull it apart on monday and see if I can fix it up. I know nothing about carbies, as this is the first one I have ever played with. I need to find out the brand of carb I have an see if I can get a rebuild kit for it, although a whole new carb is only about $120 or so.

If the needle and seat are not sealing properly, could I use some fine lapping compound and match the needle and seat similarly to valves? I know this is not ideal, but it may work as a temporary fix.

Is it a Solex carby? Then this kit is what you want:

Simple job to take the top off the carb - check that the float is good, take the N&S valve out & blow into it - test it by pushing in the button.

The N&S valve is the same design for all these Solex carbs, maybe yours has a wrong spec from a Renault or Peugeot???

I got a bit worried when I saw you pouring too much petrol into the carbi. One of my mates (Bernard - a firey) set fire to himself doing it that way.

Just use one of these instead, much more delicate :

I have done a few carbys. Stromberg, Holley, Solex, etc. Kit and a clean seemed like that's all I need.

Years later I learned.

Your butterfly shaft will be worn and or it's seat leaking air giving you the wrong air/fuel mix on startup.

A NEW carb at 120 bucks...

This.  For $120 it’s not even a conversation we should be having.  I bet your fancy whitewall things cost more than that.

Actually the white walls cost less ;) 

It is definitely not the money for the new carb, I would prefer to actually learn something, than just bolt on a new one and be done. I will pull it apart on Monday and see what we have.

You do have to have a go hey? I do the same.

You may as well know, I've never had a carby down entirely that didn't have water induced corrosion within the internal channels. 

Some of these channels  sealed after production. I know there were people reconditioning them years ago, that is cleaning the internals of the main block. 

If anyone can do it you will.
