Thanks for the info. My pulley is a little different, instead of the U shaped "dimple" being on the left, it is on the right. I set the timing to where the V is at the center of the case, but could only get 700-750 rpm with it there, but after I plugged the idle sabeliser in, the RPM jumped to about 850-900 RPM. I did notice while watching the flash on the timing light, that every once in a while, it misses a flash at about the same time that the engine skips. I connected the timing light to the other plug wires and didn't have that problem most of the time (it happened but about 1 10th of the time) I rebuilt everything that didn't require cracking the case. It wasn't too bad except that it took a lot longer than I expected (about 5 days). I purchased all of my parts from Fast German Auto. They have extremely good prices and give excellent advice, but I like the convenience that The Bus Depot offers with the check by phone.

The mark closest to the engine crankcase is a sharp cut V. On the same pulley, the second mark is a small dimple about 7 mm to the left on the further edge of the pulley. I believe (if memory serves me correct) that the V is 5 degrees ATDC and the dimple is TDC. You can verify just by rotating the engine and seeing which mark comes first. To adjust the timing, disconnect the idle stabilizer and set the idle speed to 850. Using your timing light, rotate the distributor until the V lines up with the center split in the crankcase. I noticed an interesting thing with my engine. On the oil flap door (where the license plate is), there is a sticker that says the correct idle speed is 750 and the timing is not-adjustable? But since I have a DH engine, I followed the recommendations in the Bentley. Anyone else have a similar sticker? By the way, this week I pulled my engine to do a rebuild. How hard was it to do a rebuild? Where did you buy your parts? Did you rebuild the crankcase?
