View Full Version : Carb Questions

Does anyone know what car comes on a 2000 Outback? I know it is a Holley brand but I do not know if it is a 600cfm or a 750cfm...

I'd bet it's a 600 or 650cfm carb. 750cfm is a lot of air moving through it and generally a small block cannot move that kind of unless the heads have been seriously ported.

Just out of curiosity why the question?

When I go to hit the gas it has a miss... You have to feather the gas to make it go. Once it goes it is fine. It is just getting it going.

Accelerator pump diaphram?

I'm guessing it's probably the idle circuit. If it was the fuel pump theoretically it would apply throughout the full range. Sounds like it's time for a rebuild or replace. See if you have a shop locally that does marine rebuilds. There are a bunch of reputable places on the web that offer exchanges for rebuilds with warrenties.

Just stay as far as you can from this place, Carbcare USA/ (http://www.carbcareusa.com/)! Took me six months and at least a dozen calls to get a refund from him on a returned carb from an old boat i had! :mad:

I recommend you rebuild the carb you have if you buy a rebuilt unit you will get parts from multiple carbs. There are slight variations in different years
and different carbs. Better to keep the original carb then you know what you have. Call Skidim they will help you with your carb identity. They have kits and new units for you boat. Good Luck

I have been trying to decide weather to find someone to rebuild mine or order new. I will not order a rebuilt one,,,it will be new if I go that route. I have found the kits to do it but I hve not had any luck finding some one local to build it...

Who is Skidim?

Does anyone know weather it is a 600 or 750. Those are the only ones Holley offers for replacement

Like i said there's no way it's a 750 unless your sporting a big block or a juiced small block. Take the numbers off of it and call Holley, they'll tell you.

Thanks for all the help!! I ordered a new Holley 600 from Summitt, I thought that would be the best route.
