Disclaimer, this is a bitchy thread but I just want to start some conversation.
I'll start my question by giving some background. I bought a 1973 FJ40 with the original motor a few years ago and I rebuilt the motor. Mechanically, the engine should be near perfect. Unfortunately, one of the previous owners replaced my carb with a weber 32/36. It was auto choke. All crummy inside and in dire need of replacement.
Because I didn't know better, and because I was told by several people that it was a sufficient carb, I replaced it with a brand new manual-choke version of the same carburetor.
I tuned it, I've had it professionally tuned and jetted, and STILL it doesn't run right. The best way I can describe it... It just doesn't have a 'sweet spot'. It's either too lean for the freeway or it's too rich to idle without dieseling. And I can't trust it to start if it's been sitting more than 48 hours. This part is the scariest to me, because I'm driving a Toyota Land Cruiser gosh dammit. Not a Kia.
So, what's the truth? I've heard webers are great, I've heard they suck; I've heard the Aisin carbs are great, and I've also heard that they suck too. I kinda want some numbers on the CFM these motors require. Or at least to hear from someone who really knows their s***. I know it's an old truck, but it's also a Toyota. Running perfect shouldn't be too much to ask.
