Can you help me with my crazy truck part 2

[kilam68]

I have a 79 fullsize jimmy.  I had a problem with the engine shutting down as soon as I got to the corner of the my street.  Then I starting doing what you guys say not to - I started throwing parts at it.  I replaced the distributor, the cap coil fuel filter fuel pump and the carburetor.  Now the carburetor spitts gas into the air backfires and causes a fire in the carb. There is a thread on this forum where a guy had the same problem.  he fixed it but didnt know what he did.  Any suggestions?

You replaced the entire distributor? Sounds like its 180 degrees out to me, by your description that it back fires into the carb.

that’s something I never understood if its 180 out it should run fine at least in my head it should but if its advanced a bit while being 180 out then yes it would back fire out the carb same way as if it was in the right position but advanced a little bit. when I first got my 86 I took it to a mechanic to get it to pass Delaware’s tail pipe sniffer "emissions" he told me only 50 bucks so I let him work on it came back next day he told me my dis was 180 out charged me another 40 bucks just to fix that. lets just say I felt a little ripped and ever since then I never let anyone but me or friends work on my trucks or even families, if they tell me " well I got to take the van to the dealer cause the battery keeps dying or the check engine light is on I tell them to cancel the appointment and ill be over to fix it

OK I will admit my lack of knowledge to help other newbies having the same issue.  I fixed the problem of the carburetor spitting gas by changing the distributor from being set on the #2 cylinder to being set on #1.  I felt like a dumass and a genius at the same time when it started up.  But I still have my original problem.  The engine dies when I step on the gas.  I will start another thread for that. Thanks for all of your help.

why start another thread this one is just fine

OK more info on the truck ex what type of carb size and make. engine size, how full is the tank now and when this happens. when you say does this at the corner of your street you mean when you take the corner or about that distance away from your house. does it die then just pick right up and take off?

The crankshaft rotates 720° to complete one cycle. If your distributor is off 180° but in the correct firing order, you'd be delivering spark on the exhaust stroke not on the compression stroke.

now I'm confused. Lol but why would mine run fine well kind of

Irish, sounds like you're off a tooth, not 180°

Irish, Your truck did not run 180*...There is something else with the story

he told me my dis was 180 out charged me another 40 bucks just to fix that.

If you drove it there & the timing chain didn't slip "exactly" 180* when you shut it off or when the mechanic started it...somethings doesn't add up. My thought is he set the timing correctly, maybe he pulled the distributor to move it a tooth to get the "correct swing" on the vacuum advance, or someone had it wired "not by the book", so he fixed that?
