Check the float? I haven't had a carb vehicle in a while, but seem to recall that was a sticking point with the vw carb. dp |

carb problem???
The idle circuit is blocked.
You have to dismantle and blow the carb passages and jets with compressed air. Also check that the electromagnetic cut-off valve clicks when you turn the ignition switch on. You won't have idle if this doesn't work. Have someone turn on-off the ignition switch, and listen for a click from the carb. If it doesn't click, remove the solenoid and check it directly on a battery. Replace it if it doesn't click, or fix the electrical connections. Gas is dripping from the butterfly shaft, because the bushings are worn. When you press the gas to keep it running, raw gas is sprayed on the butterfly from the accelerator pump, part of which ends to drip through the worn throttle shaft bushings. If you take the carb of for cleaning, you have to point the U shaped accelerator pump jet, so that it injects the fuel stream to the side of the butterfly, through the butterfly opening, directly down the carb's throat. If the shaft bushings are very worn, it won't be possible to adjust the carb to a steady idle (a variable vacuum leak is caused around the shaft), but they must be very worn to render the carb unusable.

carb problem???
I don't know about mechanics or labor in Texas, I live in Greece.
But -IF- you can find a GOOD mechanic with EXPERIENCE on old VWs, it would only take him 30 minutes to do a full cleaning, install a new gasket set and adjust idle. A good quality carb rebuild kit (gasket set) costs around $14. If the carb was recently rebuilt, you won't need new gaskets (unless they are damaged during disassembly). $50 would be a fair price in Greece, but I would prefer to do it myself, cheaper plus knowing I did the job correctly. It is very easy to do it yourself. If you don't hate getting your hands dirty, you should attempt it. You will only need a new gasket set, and an air compressor. If you don't own an air compressor you can take the parts, after you clean the crud off them, to a gas station to blow the passages and jets. Adjusting the carb does not require any special equipment. And if you have any questions we can always help. Plus you will know how to do it next time, in half hour. Just ask.

carb problem???
I would quickly take off the idle jet and clean it out before cleaning the
entire carb. After 5 minutes you will be back idling usually! <g> If that does not work then take off the carb and clean well. Kit is usually needed along with a good fuel filter. ;-) -- later, dave (One out of many daves) "Bill Spiliotopoulos" > wrote in message ... >I don't know about mechanics or labor in Texas, I live in Greece. > But -IF- you can find a GOOD mechanic with EXPERIENCE on old VWs, it would > only take him 30 minutes to do a full cleaning, install a new gasket set > and adjust idle. > A good quality carb rebuild kit (gasket set) costs around $14.

carb problem???
The idle jet is the brass hex nut on the right side, near the alternator.
If there are 2 jets to the right, the idle jet is the one that look straight to the right, and not te one that looks 45 degrees to the back. What carburator do you have? Did you check the solenoid? Did you adjusted the idle speed from the screws to the left and adjusted the throttle buterfly almost completely closed? Bill Spiliotopoulos, '67 Bug. ?
