Okay I am new to the scene. Just bought a 87 Yota 4x4 22r. Some jamoke put a weber on it with the water choke.
When I start it up it immediately tries to go dead unless I pat the gas. Now if I hold the butterflies closed from the top it idles like a champion.
Is this an issue with the water choke or an issue with the spring on the butterflies, (maybe preventing them from shutting all the way)?

Again I'm new to the scene and don't have anyone around the Mobile, AL area that I know can work on these carbs.

Thanks,

Adam

 

Hey I'm in Mobile. Don't know squat about carbs though. I'm a EFI guy

 

Do you know anyone who does? I thought about TDC but I don't know if they would bother fooling with my old truck.

 

Does it do it all the time? Cold starts, warm starts? Is it drivable?

 

I just bought it 3 days ago. I can drive it but when I clutch in to stop it goes dead. I'm thinking about just buying a new one with electric choke and starting over.

 

I'm not familiar with the term "water choke", but I assume it's an automatic choke that senses the coolant temperature to determine whether the choke butterfly should be closed (cold) or open (hot), or somewhere in between. Assuming the PO actually connected the sensor to the coolant system somewhere, there's probably a dial or spring on the side of the butterfly that needs adjusting to get the butterfly fully closed at cold temperatures and fully open when the engine is warmed up. Usually you just loosen a locking screw and rotate the dial until the butterfly just fully closes when the engine is cold.

Most auto chokes used a bi-metallic coil off the exhaust manifold to sense engine temperature, which is easy but doesn't track intake manifold temperature accurately, leading to hard starting under certain conditions. The coolant temp sensor (water choke) sounds like a better idea.

Worst case, though, just put a manual cable on it with a knob in the cab and manage the choke yourself. Once you get the hang of it, it'll work better than any automatic choke.

Number 45 on the schematics is the water chamber. Which is the one installed on my carb. I also said I am very new to these carbs. I just went ahead and bought a new one with an electric choke. I don't feel like fooling with the "water choke".
