Hi all, Not sure if I'm in the right forum for this but everyone here seems to be helpful anyway so here goes. This afternoon I noticed the advance timing is not working on my 1958 chevy 3800 1 ton truck. 235 engine, everyrhing stock from factory. I have a couple older posts here but couldn't find the "create new post" link, so this is where I ended up. Can anyone tell Me why tge advance timing (attached to distributor) would not be moving as I move the accelerator? Doing this under the hood by hand obviously, and as I'm pulling the accelerator linkage I'm warching the dist not moving at all. Concerned as to why this may be. I appreciate any help with this, thank you in advance.
