detonation problem

[86c20]

ok so i looked at the dissy tonight the rotor points to the back of the carb not to number 1 so its a tooth off. rotated the wires and could not get her to start. counter clockwise. and move dissy as mush as i could no start. i think i might have found another problem thats not helping much either. its geting better but can still hear it some. i need a plug for the manifoid. the air tube rusted off. its the big one tube not the 4 littles any one know what size and thread it would be? also when i did the water pump i took off the air pump tubes and alot of vacc lines that wheere not needed any more. i know have the dissy going to the pass side port on the stock qjet. is this the right one? seems to run better that way. also the advance in the dissy is working as you can hear a change when pluged or unpluged
