How do I adjust the rotar button to point to the number one cylinder?

first determine which cylander is number 1 and which plug lead on distributer is # 1

make a mark on side of distributor body adjacent to #1 plug

make a mark on base of distributor and block so if you mess up u know where to start from again

now loosen bolt tha holds distributer in block

only loosen just enuff to move distributor,to much and distributer will move out of place again

remove distributor cap

now holding body of distributor,slowly move distributor until rotar button is pointing at #1 position

before you tighten bolt on distributer the rotor needs to be set just before top dead centre ,as the points need to open just before rotor hits #1

retighten bolt

replace distributor cap

try starting engine

the distributor can be moved by slightly loosening bolt while engine is running if timing is not exactly right
