73 340 carb replacement ?

[randy73]

Vacuum leak at the butterfly linkage, so I am going to replace w/600 or 650 carb, unless you can buy a new bottom plate?

Was thinking 600 for gas mileage, but would a 650 be better.

I ran a Carter AFB 600 on my stock 340 for years. Loved it. Got a solid 15-16 miles per gallon on the highway.

Either 600 or 650 would work - you could probably even go bigger if you wanted. I always like good throttle response though.

IF YOU WANT I think there is a dealer around here with a NOS CORRECT 340 THERMOQUAD CARB FOR AUTO CAR ( still on box ), true is 72, but better, due its the 6000 series ( better metering rods )

just in case. Of course, will require international shipping
