Greetings all - I have a '72 with a stock 1300 engine I just rebuilt. Years ago I removed the troublesome CD150 carb and replaced it with twin SU HS2s I salvaged from a 1970 Spitfire. I blocked off the vacuum port on the SU and used the Delco D204 distributor as a simple mechanical advance.
My mechanic, the great Dave Crane, advised on rebuild to replace that D204 distributor as it was getting worn. He recommended an earlier model so I could use the vacuum advance feature which he believes gives a smoother power curve in a stock car. I found a rebuilt D200 distributor on Ebay and have installed that on the car, complete with new vacuum hose. Now the fun begins. How do I time this thing? Previously I had been doing initial static timing with a slight advance and driving it to ensure no pinging. Now I'm unsure where to put the timing initially, plus the addition of the vernier adjustment on the D200 distributor has me stumped. Here's what I _think_ is correct: twist in the vernier adjustment all the way clockwise, which is full advance. Set the static timing to 0 degrees, then twist out the vernier adjustment so that 1.5 adjustments show, which would be 6 degrees ATDC. Start the engine and check it with a timing light so that it's 2 degrees ATDC at idle. The fact that I'm timing it "late", i.e., *after* TDC is what sticks in my mind as being wrong. Given that this is a later 1300 engine, I thought that I should be timing it *before* TDC by a few degrees.
