Title: How do you set timing?
Post by: txtj79 on March 13, 2009, 10:47:47 pm

Can anyone walk me through the steps to check/set my timing in my 1980 C-10 with a 350 and a Q-Jet?  Or if you know of a good page with the directions, can you point me to it?  Bare in mind, I'm not sure how to find TDC, but I do have a timing light.

Thanks,
T.J.

Locate the mark on the harmonic balancer and the zero mark on the timing pointer first. Disconnect and plug the vacuum advance. With the engine warmed up set the timing by loosening the distributor hold down clamp and rotating the distributor to acheive 10-12° btdc for your initial setting.
