Re: how to chck timing
Yes, you really need a manual to help guide you but here are the basics. Find Top Dead Center. Set the pointer. Pull all of the plugs out except plug #1. Reinstall 2-4/6 and ground if system has coil packs. With the throttle on idle check for your primary timing point buy cranking the motor and using a timing light. Disconnect the throttle linkage and place throttle to wide open throttle check again for timing advance setting.
Here are the basics but you need the manual to know how to make the proper adjustments.
