Just built this guy with stock web cam, rebuilt heads, blah blah. Thanks to Jakes video this thing doesn't leak a drop of oil (IMG:style_emoticons/default/beerchug.gif) . After I first cranked it and set timing this thing hummed with no stumble. After a little driving this stumble began and now will not go away. I went and double checked the TBS and all is well there. It still looks new on the inside with little to no wear. This engine had 60k original miles when I rebuilt. The harness has been tested. I tore down and put back together the distributor w/ the Bosch grease. I am still using points/condenser. The trigger points looked ok and are definitely clean. Any thoughts outside replacing the trigger points? Could a stumble be caused by any other of the components? Again, the problem was not there at first. I am thinking I might yank the compufire off of my bug and throw it in there to see what happens...All thoughts are appreciated. (IMG:style_emoticons/default/beer3.gif)

Even if the trigger points contacts look good, the dogs that ride the cam can wear out. When this happens, they don't open and close completely. I would re-evaluate those for sure. Verify you have the correct head temp sensor with the correct resistor(if required, depending on your year). Check for loose connections/bad grounds too.

I had a miss like that, I tried new throttle switch ,re-timing ,new sensor still had the miss. Finally changed trigger points it worked no more miss.
