I picked up an '86 W250 recently. It has a Rochester Quad on it. The engine runs fine but I am being blinded by the HC's it's emitting. The fuel pressure is 7psi so that's OK. I'm considering either rebuilding it or getting a replacement such as a TBI or something that eliminates a float bowl. Can I get some recommendations on this? Thanks.

 

Welcome.

If it's a Quadrajet with tight throttle shafts I'd rebuild it, GREAT carb.

 

Either and Edelbrock Carb or a Holley stand alone TBI setup. Check out Jegs Performance online. I'm sure they have what you are looking for.
