Sounds like the valve adjustments are all out.
Here's what you can do & it is very simple with the rocker & side cover off:
1. get No 1 @ TDC compression on your timing gear cover marker & adjust both Number 1 valves to correct clearance (Wes told you).
2. put a chalk mark on the front belt pulley 180 degrees from your timing mark (directly opposite the real timing mark).
3. carefully rotate the engine JUST 180 degrees in correct DOR so that the chalk mark is now @ the timing mark on the gear cover
& adjust valves to correct clearance on Number 3
4. rotate engine 180 degrees so your timing marks line up & adjust vales to correct clearances on Number 4
5. rotate engine 180 degrees so the chalk mark now lines up & adjust Number 2 to correct clearances.
You are all DONE....how simple can it get?
The basis of this is you have a 4 cylinder 4 cycle engine in which all cylinders have fired in 720 degrees or 2 full crank rotations. This means each cylinder fires in turn every 180 degrees in the correct firing order (4 X 180= 720).
When one cylinder is firing both is valves are fully closed & should be gapped there.
Its opposite number is in the same position TDC but its valves positions are in what is called on the rock (neither opened or closed)
