Thread: Rochester jet size ?

Tweet

I have a small v-6 approx 225 cubic inches...basically stock with headers.

Carb is a rochester 2 barrel 2 jet..........no running info on the engine, rebuilding the carb now, not sure if the carb is stock to this motor or not., rebuild is because it was super rich at idle, hesitated,black smoked and was seeping/leaking thru the gaskets.


Current jet size that was in the carb are 52`s....I am not super familiar with carb jetting so I have no idea if this is middle of the road, way too small or way oversized for my application.......

Thought I might as well change them if needed while it is apart.....

I kow the only way to know for sure is readig the plugs,vac readings etc........just wanted to get in the ballpark to start with.

Any advice appreciated, thanks
