This was a helpful video for me, I have a '70 cutlass that is running lean and I believe it may have the original jets in it, so with today's oxygenated fuel I need to richen it with a larger jet (2 sizes up is the recommendation, but i'll keep reading the plugs until i get it right). This was only to-the-point resource i could find to simply change the jet. Like you, there are some of us out here still running the 2G's. By the way, as i understand it the 2G is manual choke, the 2GV (like yours) is a "divorced" choke pull-off where the bimetal spring is not attached to the carb but is in the intake manifold, and the 2GC (I have this) has the bimetal spring in a housing attached to the side of the carb. There is a metal stove pipe that loops down from this housing into the manifold, which heats up the spring.
That's great man, I'm glad the video wasn't for nothing. Thank you very much for watching, & for your comment; that info may help someone else one of these days. Glad I can be a part of this community.
I think that was the carb on my '72 Skylark, that was so long ago. It had a spacer underneath it too. If I floored it from a stop, sometimes it would hesitate and smoke would come out the hood scoops. It looked like a dragon breathing out smoke. I still kick myself for selling that car 32 years ago. Do what you can to keep the Chevelle running and enjoy it. Don't sell it and regret it the rest of your life.
@CrowVelle Hey Man! I saw this video of yours like two weeks ago but i just the time today to post a late comment. Good to see you back. :) Hope were gonna see some more videos from you cowboy haha!
Rochester dual jet carb. My 69 chevelle HAD that carb. When I bought it in '95. It was a new carb. Too. I ditched it for a rochester quadrajet, made a world of difference, in driveability, power, and gas mileage. Yup, the quadrajet can do better mileage than a dual jet, reason, the size of the primary barrels. Either way, they are fun cars arent they
im just kinda curious im looking at that distributor and maybe im way off but that looks to far advanced to me and that would make me wonder if your firing before the piston is coming up that would cause pinging and maybe with more fuel its not making it run lean. but i am curious of what size jet you put in those and where did you get them, the other question is are you running a fuel filter in front of the fuel pump, i did that and it actually starved my carburetor for gas.
What's your average mpg? Is it livable on a daily basis? I know my V6 Malibu and Bonneville were about 18-20 around town and 22-24 highway. My Skylark would get about 18 mpg highway with the top up.
