Just wondering how to tell when #1 cylinder on va is going to fire and which is 1 the rad or tank side and info would be great thanks
 
number one is the one at the front near the radiator, you can tell it is on the compression stroke which is the one it fires on by removing the plug turning the motor over with you finger over the hole and feeling for compression, also remove the dist. cap and the rotor button should point to the wire going to the number 1 plug.
 
As Mackdog said, remove the #1 spark plug and put your finger over the spark plug hole as you slowly turn the motor over by hand. Make sure you rotate it the correct direction. Once you find the compression stroke either shine a light in the spark plug hole or put a thin screwdriver in the hole and continue to slowly rotate the motor until the screwdriver stops moving up. This will be top-dead-center. Then like Mackdog said you can remove the distributer cap and locate #1 one wire. The rotor should be pointing to #1 at this time. If not you will need to rearrange the spark plug wires or pull the distributor and align it so that the rotor does point to # 1. Make sure that you match the spark plug wires with the direction that the rotor turns.
