Backfiring
Took the Blazer out for a trip around the block today, just to see how things were going and its backfiring through the carb. Checked the timing, it was off a little, so reset that. Still backfiring. Only does it when I step on the gas or it starts to lug hard. Idling is fine.
This is a 350 with HEI and an Edelbrock carb. Checked the wires, nothing touching, seem to be all in the right place. I also had rebuilt the carb not long ago, so don't think its that. I had thought it was my fuel pump and then it went out, so I just replaced it, so think the fuel pump is ok. You guys have any other idea's? The haynes manual says maybe improperly adjusted valves, but not sure how I would check that. They aren't clattering.
