Carb pump diacharge nozzle

Hi all,

I was about to put my carb back on when I noticed it is missing a nozzle. What is the best way to determine what size I need? Would it be the same as the other one?

Thanks,

-Mike

No it isn't. Your vac secondary carb only has one accelerator pump, not two. There are no secondary nozzles.

Holley used that same main body casting on a lot of different carbs. Some had two squirters, some didn't.

That looks a ton like an 1850 to me. 600 CFM vacuum secondary with a single feed to the front bowl and a transfer tube for the rear bowl and a single accelerator pump.
