Sorry, didn't include all the details. Take the rotor off (disconnect the fuel pump relay while doing all of this too). With all spark plugs but one off, then watch the rotor as it cranks, and see if the engine 'slows' down a bit when it comes to the cylinder (I typically use number one) and verify that the rotor is close to TDC as it spins around. You can also do this by hand too - the engine will resist you as you try to crank it on that one cylinder. If your cam timing is messed up, then you won't have compression building up to where the rotor hits the mark on the distributor.

Make sense?

I still think it sounds like an electrical problem. The popping tells me that you have some fuel, some spark, and some compression. Fuel and compression are rarely the problem in a case like this, so the remainder is spark.

Hey, just remembered - the 911SC distributor runs backwards from almost all other 911s. So, if you use a wiring diagram from another car, it won't work properly. The firing order is the same (1-6-2-4-3-5) but the distributor runs *counter-clockwise*. Make sure that this is setup properly, as it will give the exact results that you are getting...
