What is the timing marks for a 1998 350 Big Bear 4x4
no
I could be wrong, but I have a Vortec 350 in a GMC truck and I think the computer handles the ignition timing. If your talking about valve timing I would assume there are marks on the timing gears like the days of old, but I haven't torn the timing cover off of mine yet.
There is no more timing marks for a 98 vortec you have to go off marks on distribitor & use a scanner. You are setting cam timing
The timing marks should be found on a little metal plate directly above the harmonic balancer.
The timing marks can assist a mechanic in setting the engine timing. The number one timing marks will set the number one piston so that the number one valve can be properly adjusted.
clean on the front of the pump on top where it bolts on the motor there are timing marks there line up the long marks to set the timing.
You set cam timing on a Yamaha big bear 350 4x4, by opening up the bike chassis and looking for the cam timing levers. You can adjust it up or down until you have it set to how you want it.
line up timing marks from harmonic balancer and timing tab on timing cover

timing is computer controled base timing is done when gears are put on and timing marks are allined. there is not normally a timing problem there can be problems with sensors and wiring or pcm/ficm.
