Post subject:  adjusting the choke

I was curious if there is a certain way that the choke should be adjusted? One of my issues with my SC has been that it idles too high. I have tried many ways to adjust the carb to get the RPMs lower but nothing has really worked. If I manually push the accelerator lever back into position, it is met by the choke lever

If I let go over the throttle lever, it will move away from the choke lever a little causing the RPM to get higher obviously.

So I know if I loosen the 3 screws I can move the choke. Is there any particular instructions on how to do this or any "watch out for this"??

Do you have a 34 pict or a 30/31?

30/31

With the engine cold not running air filter off pull on the accelerator lever,
notice how far the choke butterfly closes. Loosen the 3 screws on the choke and turn the choke body
clock wise until you see the choke butterfly start to open. This is a good starting point.
when the engine is all warmed up the butterfly should be open all the way.

the diagram you have above is the correct position for the choke lever when the engine is at running temperature.
You can back out the screw on the accelerator lever if you want to lower the rps.
Also your carb may need adjusting.

^^ yes to everything Chris said. Adjustments on the 34 are completely different from the 30/31 so thus my question.

If the carb continues to give you problems consider going to a German rebuild from Tim at Volkzbitz on the Samba.

You are correct, after many problems with the performance I switched to a German 34 and it made all the difference!
