New carb for a 250 L6?
 

Recently I've started to notice some hiccups in the performance of my carburetor so I've decided to buy a new one. The only thing that I am stuck on is do I buy another 1 barrel or a 2 barrel? What are your opinions/experiences with these?

Use the search function and look for Weber carb setups. They are progressive 2 barrel carbs that will bolt to your inline 6 manifold with an adapter. You’ll need to convert to a cable style gas pedal and throttle cable.
Tom Langdon sells the parts you’ll need. Look around on his website. LINK HERE

I had my Rochester B one barrel carb rebuilt and I’m pretty happy. Starts up easy and has done well. I think my HEI distributor has helped a lot too.

Be aware of local auto parts store rebuilt one barrel carbs. They are pieced together from multiple units and sometimes dinged pretty bad. I haven't had luck with them in the past and decided to start rebuilding them myself. I keep two or three used but good units in my garage just for that purpose.

I agree with 68gmsee. Best bet is to find an original that needs rebuilding and rebuild yourself or send to a shop that will rebuild YOUR carb. My 1965 carb still had the original Rochester tag.

2 barrel holleys or webers are good choices. 2 barrel weber 32/36 is a decent choice.

I have the Weber 32/36 and have been quite pleased with it. If I knew anything about carb tuning I would probably be even happier with it.

What kind of MPGs are you getting?

Re: New carb for a 250 L6?
 

Last time I paid attention was right around 15 mpg.

Fifteen MPG is pretty good for a half ton of tin and the aerodynamics of a brick.
