Hey Guys,

I'm torn. I love these classic cars, but the carbs stuff is very new to me, and I've only ever driven fuel injected cars. The though of having to pull idle jets and get this and that different screw and whoosits to set it right is making me shy away from it.

I just dont know if I should go for fuel injection, as it seems rather expensive.

What should I do?

I kinda would like the ability to set the fuel injection up and forget it, but at least carbs are dead simple, from a plumbing perspective.

I would like some good power, but also a streetable car. Are carbs so bad that you cant rely on the car at all?

when you turn the sender upside down, repeatedly, the float should move freely, repeatedly. yes, unregulated fuel pressure is a bad thing for the needle valves that live in the float chambers of the carbs. more than likely running horribly rich. i would say impossible to get them dialed in. your car was waiting for a new, kind, loving owner. if you're fighting your carbs you MUST address the issues upstream first. then deal with dialing them in.

with the 2 strokers I could tell if it was rich or not by the smoke out of the pipe and the general way the engines ran. With this setup I have NO idea if it's rich or not. All I know is that when I come coasting to a stop, the smell is pretty bad. I pass priuses and think that I'm polluting enough for a fleet of those things. (I used to own one, not bad cars, drive horribly though)

It smells pretty bad, in other words. Does that indicate running rich? It was hesitating at low throttle, and lacked ANY kind of power above 3k rpm. Is this a combination of things from the dizzy being a POS with a poor advance curve, running rich, and bad fuel flow volume?
