I want to change my 009 to a vacuum dizzy and I'm having a problem timing it because of the dual post temp sensor I have. The canister will only allow me to turn it so far until the bottom part hits the sensor. So I can't get any more timing on it. Yes, I could take out the sensor and put back in the single post, but I would like to get around that if I can. Any ideas?

It's the alignment of the drive gear. You could remove the distributor drive and install it a few teeth cw or ccw, but the thrust shims could fall into the engine.

You could drive the roll pin out of the drive dog on the distributo and install it 180 degrees off.

Our you could rotate the spark plug wire and set them 90 degrees off.

Make sense????

I thought about the spark plug wire thing, but then I thought TDC wouldn't be #1 anymore and I didn't want to confuse myself later. I have already replaced the distributor shaft with a good used one. So, all I have to do is take it apart and turn it a little? I can do that. I'm not sure what you mean by the thrust bearings. Could you explain?

There are 2 thrust washers that go under the distributor drive shaft and prevent the harden shaft from machining it's self into the soft magnesium case. When you pull the drive shaft out, the washers could fall into the engine.

That causes 2 problems. One is the washers are not there protecting the case. The other is there's 2 large washers floating around inside.

#7 is the drive shaft
#9 is the shim

Yea, but that's on the distributor right? I just pulled the whole thing out and did it on my bench. Unless I'm missing something?

Now i'm confused. I'm talking about the drive shaft that's driven off the crankshaft. Not the actual distributor.

Oh, no, no, no. I know that part is correct because I had on a vacuum dizzy originally before I went to the 009. I'm talking about the dizzy shaft. So, see, we were talking about two different things, but you gave me an idea. Since I replaced the dizzy shaft (because mine was worn and sloppy) with a good used one, can't I just take it back out and turn it so it would give me more room to time it?

That's not going to work, is it. Did anybody else have this problem or am I just going to have to break down and take the dual post out?

Just thought I'd let you guys know I was a ditz and solved this problem. The dual sensor does have a flat spot on it, so the canister just touches it but still able to get as much timing as you need. I ended up trashing it anyway, because it wasn't working right. I'd stand there looking at the engine running and all of a sudden the idle would go real high. As soon as I disconnected the vacuum hose it came back down. It was used anyways, I'll buy another one later.
