Got to mess with blazer just a little this weekend. I am having a little bit of a issue of popping thru the exhaust. It's kinda sparatic. It will not do it idling, but it seems after u drive around a little bit it will pop thru the exhaust sparaticly. So, I have changed the points to petronix, new cap, new rotor, new cool, new spark plugs. Put a rebuilt quadrajet on it, old one looks like someone had rebuilt it a few times. Put new base plate carb gasket on, new vacuum lines on and new rubber caps for lines no used. Still popping. Old
Carb front barrels were black. Going to go ahead and put new spark plug wires on this week and crawl under it and check for exhaust leak. Manifolds seem good, but it sounds like i here a popping noise at mufflers. Put new fuel filter, may put new fuel
Pump on even though I don't think that's it.
