I finally had some time to fire it up and give it a drive from cold today. Fired on the first crank - easier than my GTO! (Been following the fuel evaporation thread.)

No need to warm it up for an...

Mike's carburetor parts. He has a lot of 2bbl videos on YouTube that were really helpful. The kit was good quality, but not much different than what I got from O'Reilly other than it being more...

I think we pretty much have this solved now, thanks for all the help. The car runs much better when cold after some choke adjustments. The choke was opening way too early when the engine was cold, so...

I didn't expect the jets to change anything at idle. While it's not overly lean during regular driving, since I had it apart I did see some room to richen it up a little.

This morning it still...

Got the carb parts today and installed a fresh kit along with a new power valve, power piston and accelerator pump with associated springs. I made sure all the passages were clean and went up two jet...

The new vacuum advance made the spike go down to around 15:1, so it helped, but I'm looking for that momentarily rich dip that Schurkey mentioned. I did adjust the idle down to 13.5.

I'm out of...

New vacuum advance didn't fully fix it, but it's better than it was. I am getting a full 36 degrees of advance now, too. I ran it with and without the EGR connected to vacuum. It actually seems to...

Sounds like the EGR situation may not be helping. Th valve is still installed, I just unhooked the vacuum to it. The thermostat is switch is long gone and all the vacuum lines were rotted. With all...

It’s hard to say when this started. The car sat for 6 years before we got it. We did a bunch of things to get it roadworthy.

I went through and thoroughly cleaned the carb including removing the...

It pulls a steady 19 inches of vacuum at idle, but I haven't left a gauge plugged in while we're driving to see what's going on. I picked up a new vacuum advance anticipating this potentially being a...

It has a power valve in the bottom of the fuel bowl between the jets that's spring loaded. No metering rods like a QJ.

I had the idle mixture richer (13.4) before I plugged in the 02 sensor and...

'74 Ventura 2bbl lean condition

The 2bbl (7043062) on our '74 Ventura 350 has an off idle stumble that I've been trying to resolve. It's really pronounced when the engine is cold, so much that it will backfire or stall sometimes,...
