I think you need to stop and spend some time thinking this out, instead of just trying one thing after another. My GUESS is that the distributor drive gear is installed wrong and that some of your distributors have been modified to accommodate this. First: Check your engine. Turn it to #1 TDC (verified at the valves) and check the position of the dist drive gear. DON'T turn the engine forward with the distributor out!!! Check the drive gear position against what the Bentley shows. If the drive gear is in wrong. Fix it. Don't just modify another distributor--that's what got you in this jam. Next: Get out your Bentley and look at the exploded view of the type 3 distributor. Look at the relation between the wide space on the drive dog and the direction the rotor points. If you place the dist upright with the wide side of the drive dog away from you, then the rotor should point away from you and to the right. If it is wrong, they you have to drive out the pin that holds the drive dog in place and flip the drive dog 180 degrees. Check ALL your type 3 distributors. I think type 1 distributors may be different, so that could also cause problems. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
