Carb. question, rebuild or just buy a new one?

[mustanger]

The carb I have now is a Holley 650 DP, it runs ok but I have a small issue with a slight studder, it's enough to bug the piss out of me so I'm thinking, should I buy the rebuild kit for it or just buy a new one. I figure the one I have now is at least 10 years old. I'm new to this, so I'm still not sure which way to go.
Maybe some of you carb guys can lend me some advise, I'd really appreciate it:bigthumb

On a side note....I got my vacuum leak plugged which fixed my idle/surge issues.

Well....if you know how to rebuild it, and your metering blocks aren't warped and everything else is in good condition, why buy a new one? If you don't know how to rebuild, you might make your issues worse. I'd suggest either getting help or paying someone who knows what they're doing unless you're adventurous and wanna tackle it yourself. I rebuilt mine the first time and it was pretty straight forward...just pay attention and remember how it goes back together. If you can adjust the floats and corner idle screws then you shouldn't have any issue with rebuidling it.

Yea...it's like a hicup I get when I come out of first to 2nd, so I think I'm going to have someone who knows what their doing rebuild, worst case scenario, if it's borked I'll buy another one, it's not as bad as I make it sound, it's something enough to really annoy the crap out of me.

I've had issues like that...sometimes they're a real bitch to sort out.

For racing reworking and rebuilding are all good in my oponion but for the street it's hard to beat new especially custom done for your combo:
I have seen some real gains in the past as well as a few of my friends with custom built carbs for our combos.

Now I'm leaning more towards the floats sticking, when I had the carb reworked it was mentioned to me about the floats and I was talking to someone tonight who seems to think the same thing.

That's really simple to fix. The needle and seat might be sticking and wore out. If you can adjust the float level then you can replace them yourself no problem.

I would get a carb kit and a set of Jet extensions. It is worth a shot. I know Cincy Speed usually has them in stock.
