Force 85 hp ignition timing

I cannot get a clear way to se

I cannot get a clear way to set the timing for my 1989 85 horse with prestolite ignition from my manual(clymer).

any thoughts

"Disconnect and ground all you

"Disconnect and ground all your plug wires (must ground them to the block or you can ruin electrical components),

Disconnect the neutral switch, I just wrap a piece of wire or tape around it to depress the switch (microswitch under the throttle tower),

connect timing light to #1 cylinder,

Advance throttle control to WOT,

have someone turn the key so the starter spins the motor and check the timing while it is spinning.

stop, adjust and recheck

set to 2 degrees less and it should be right on when it is actually running.


Good luck

Also, be careful tightening the lock nut on the timing advance screw, the pivots are plastic and will break."

thanks for the guidence Brian.
