The vacuum modulator screws into the rear there, on the PASSENGER side, but it only has a hose attached to it, no wire. There is a wire that goes in the top on the driver's side, but that doesn't screw in. Some AT 72-3 type 3s had a screw-in pressure switch on the passenger side, but that was not on the bottom or the rear and your 70 should not have it. > Bentley says to set it a 0 degrees BTDC, which is supposed to be the 2nd mark > you hit going clockwise.

Is that correct, and if so, which mark would that be? > Also, there is a mark that is much more pronounced than the others, should I > set it to that? The marks on a 70 should look like this: | | | |. The left most mark is TDC and is larger than the others. If your marks look like | | | |, then you have a 72-3 engine and TDC is the second mark from the left. > I have to pump the brake pedal to get the rear brakes to grab.

I examined the front beam and > I don't see any adjusters welded in, or any welding at all, Adjusters can be added to a beetle front end, but not to yours. The type 3 front end is different. Type 3 front ends can be adjusted, but it requires pulling things apart and setting the axle components onto different positions of the splines. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
