I need to find the center carb for a 1958 Super Marauder tri-power asap. The Holley ID number on the air horn is: R-1673A Thanks!

Good luck! There is however all 3 on ebay for $5,000. You can always make one from a regular 2bbl

Actually that guy finally lowered his price to $ 2,000.00 but it is incomplete as well

$2,000 wouldn't be bad if he had he linkages, bowls, etc. It is missing a lot. I have never seen the carbs separated but maybe you could somehow get ahold of someone who has the carbs but changed them for something else. But if it were me, I'd still keep them to have the whole setup be number correct even if I did not use them. If I ever stumble across some I will let you know. Good luck

Thanks guys. I talked to tech support at Holley and they are sending me a marine fuel bowl with a internally adjustable needle (that is not supposed to be available without buying the whole carb) which should clear the air horn of the front carb. Since this isn't a absolute restoration, it should work. We'll see. I'll let you know.

I'm familiar with the set you have (e-bay special).... go to the DIY section. There may be some information you can use.
Check for fit between the throttle plate and the main housing....
If you don't set these carbs up correctly it will never run right.....
What is the application? ....what vehicle will you use it on .?
