I'm going to try this here. I posted in the 86 section but I'm not getting any help. I think because most of those trucks are efi. So I want to you you guys where there's more carbs,,,lol.

My truck is a 87 with a carb. I watched a video where the guy talked about jumping a relay or something so it would Idle down. I was thinking that was just for efi. I don't have to mess with that do I?

His video said to pull both vacuum lines from the dist. So I assume I still need to do that. Do I need to plug them?

Also. What do I set the timing at. 5*

My light is junk. I'm off to the flea market to try and find one. I HAVE to time it now. I tried to get it close by ear. But the dist wouldn't budge. Then it moved way out of place. I couldn't get it back to where it was. Now I have a backfire out the exhaust sometimes when I let off the gas. So I gotta deal with it.

Do we have a write up or video anywhere. Thanks

 

This thread is mess, but has some info that will help you out. Carb'd trucks have vacuum advance rather than electronic, so there's no diagnostic port for you to jumper. Other than that, I don't know what I'm talking about so see if any of this helps you.
