Thanks.
So I set the timing last night and retarded it down to around 8 it was higher 
(12?). I think it is BTDC, but I forget which is which. Hah. That's a problem, 
huh? 
I was trying out the timing last night and it was probably set fine. 
So do I disconnect and plug the vacuum tube or not? 
I guess I'll try to plug it and set to 12 BTDC. I think it may have been close 
to that and then with vacuum connected again would retard to around 4 degrees. 
Hmm. 

Carbs were rebuilt (by me) and fresh 
Diaphragms. 

Anyone use a device to measure points, dwell, etc? I bought one but that may be 
specific to American cars. 
I guess I could have the dizzy rebuilt. I dread placing it back in. I recall 
that being a pain in the past. What is the opinion of the petronix (?) thingy? 
I am guessing that replaces the points? 
Thanks so much!
