Looking over my new '72 autostick, I noted that the carb had been replaced at some point with a BOCAR. Not the best quality, but whatever. Anyhow, I noticed that there are but two vac taps on the carb instead of three. The line from the rear of the carb that runs to the distributor has been T'ed and the line to the control valve added to that. Will that supply enough vac for both the control valve and dizzy withouth disturbing operation?

I still can't believe you parted ways with a 4 speed in good condition for an autostick. My recommendation would be to buy a rebuilt carb. Otherwise, run it if it can.

LOL.  I still have the 4spd Super, and the 4spd Ghia.  When you're old enough to *have to* sit in an hour or more of stop and go traffic, you'll know why I bought her.

Anyhow,  you answer doesn't help me.  I want/need to know if the single vac port is enough to run both the control vanvle and the dizzy without the two of them fighting.

Have you tried hooking up a vacuum gauge to the line to see if you still have enough pressure? That would be one way to find out. As long as you have enough vacuum, you should be cool.

I answered this a while back but somehow it disappeared.....

The tee piece should be disconnected.... as when You change gear and let the gearlever go, the control valve needs that vacuum for the auto clutch to work properly.....

 

I recently took that small vacuum hose off My weber carb to see what would happen.... well after I let the gearlever go and revved the engine to about 3000rpm the car started to move....  so the vacuum really makes a difference to the working of the auto clutch.... etc...

We only had 2 vacuum lines from the Solex Carburetors - one for the Control valve and one for the vacuum advance....  so when a 009 is added to the engine- one vacuum outlet is blocked off....

the single vacuum line from My weber was too strong for the control valve and the clutch was engaged very fast with a THUMP when I released the gear lever.... I screwed a fine threaded wood screw into the hose, cut off the head of the screw and screwed more vacuum hose onto the screw, so the screw slows the vacuum in the hose and now it works perfectly....

Best of luck

I also had this same issue, and modified the BOCAR replacement carb to have the correct port like the original Solex.  Using a drill bit (very small one), I determined the size needed to drill thru the BOCAR at the same port the Solex was located (BOCAR was plugged).  I then found a new piece of copper pipe that was the same size as the vacume hose size, and drilled and tapped this "front" section of the BOCAR and installed the copper pipe.

 

This replicated the exact same source of the vacume signal as the original Solex, and performed perfectly !

Thank guys!  I'll look into doing that, or, seeing if I can get my original Solex refitted witha  new throttle shaft bushing.

Lee,

I ran across your post on your 72 autostick and fixing the vacuum. 

I'm in the US and I'm not finding many autostick owners here. I have to reach overseas.

I had the same vacuum challenges with the "thump".  You are more expert on this..I have been fiddling as I go.  I took my autostick to a supposed VW guy..and I picked it up unable to switch gears at all..and they charged me $1600 before I could get her back.  I took a screwdriver out.and made some adjustments to my idle..to get out of there..and I drove off.

What do I need to look for..as far as the correct carburetor, the right distributor for the autostick vacuum needs?  The gears work fine when I do the best I can do by tinkering with the idle..but it seems like there is just something not quite right..

I really need some advise and would really appreciate it if you could share some wisdom.  I'm not sure what you were saying about putting a screw in the vacuum? Is that back in the vacuum reservoir adjustment screw??  How many vacuum ejection ports do you have? What carburetor?

I have a 71 Super Beetle autostick..I love it.  I'll get another stick VW..one thing at a time. 

I need help from down under.

Tina
