valve adjustment sequence on my 520ci motor

Post  speedracer on June 13th 2012, 8:55 pm

i need to find out what valves you adjust when the engines at top dead center, & when you rotate the motor back up to top dead center when the #6 piston is firing? i know this is the old way of doing it but ive been doing this by using the balancer for a long time now and thats the only way i know how. i just forgot the sequence of the valves, & lost the paper i had the info on. could use your help. thanks!

on any 4stroke engine.... EO means (Exhaust Open) adjust the intake vale just as the Exhaust valve.. Opens., and IC, means (Intake Closing) adjust the Exhaust valve after u watch the intake go all the way down and just start back up ( starting to Close, in other words )........... this works on 3hp briggs and stratton all the way to Top Fuel

When the exhuast valve opens and the intake valve just starts to close that is when you set the lash on the exhuast valve and then the same on the intake valve, when the intake valve opens and the exhuast valve just starts to close that is when you set the intake valve lash. I am sure someone will chime in if I am steering you wrong.
Good luck

when using the balancer, follow the firing order and adjust the intake and exhaust valves . Start with #1 at top dead center on the power stroke ( after the intake valve closes). turn the crank 90 degrees at a time
