Edelbrock 1406 disassembly question

[Greg Fowler]

I have chased down my fuel problem to the carbeurator. Fuel is getting to the carb but the engine won't fire. I put a little fuel in the carb and it started right up for 3-5 seconds then stopped.

I decided to see if there was some blockage in the carb. I have removed it from the manifold and I am trying to remove the top section but it doesn't want to yield. i have all the torx bolts off. Should I pry more vigorously? I think I have to get to the bowls by removing this top section.

Am I going down the wrong road?

thanks for any thoughts, Greg

Once you figure it out, make sure to bolt up a Holley and you should be fine.

Greg:

I also am not a fan of Edlebrock carbs, but it sounds like you need a hand. Here are tuning tips and a rebuild guide.

Toss it , Been there*.

After you remove the torx's removed the cover to remove the pistons/springs/needles. It really should just come apart, no big deal.

If you think it's running out of fuel, let it stall and then work the accellerator pump and note if it shoots fuel. If not it's indeed running dry. Probably a fuel delivery problem not a carb problem. What fuel delivery system are you running?

Have you run or cycled the fuel pump to see if you're getting fuel to the carb? You should start there.

Thanks for the links, and for all the replies. I found that it came apart much easier when you remove the central bolt!

Everything looked clean. I could not find any evidence of blockage but then I am not really a mechanic.

I will look at the links given and see where that takes me. The car has sat for about 10 months. It turns over strong as ever. Fuel is getting to the carb. It baffles me because I have never had an issue with it for the last 8 years until now.

Again, thanks guys.

ohm, the fuel delivery is electronically pumped.

Greg check the needle and seat to be sure bowl is filling with fuel.
Next blow out all the jets,main and idle jets to be sure no garbage is in them.
When you move the accelerator arm when looking down carb throat,to you see fuel shoot out the squirters.
If so floats are likely not the problem as fuel bowl is filling enough to charge accelerator curcuit.
Fuel squirts from accel pump, but not start. Clean jets AND check choke operation.

I found that the rubber plug/cover over the vacuum had cracked. Perhaps it was to heat or age. Would a lack of vacuum prevent startup?
