I have a Weber 4bbl from my 96' Merc. 7.4L that needs to be rebuilt. Anyone out there have someone they would refer me too? Thanks.

I am extremely happy with their work.

Thanks RLW, I'll give them a call today.

Nickerson seems to be the one!!

My blower carbs set up by Nickerson are great!

Those carbs are very simple. You could do it yourself if you have any mechanical ability.
If I was going to set up a carb, I would also send it to Nickerson. But for a simple rebuild, there is certainly a carb shop near you that can do it. Check the Yellow pages for "carburetor". Cost should be under $100.

Thanks everyone! I contacted Nickerson and they wouldn't rebuild it, only sell me a new Holley for $900+ which out of my league. I was going to rebuild myself and the rebuild kit are around $95 but I'v never done one before. Do some kits come with instructions?

95$ for a rebuild kit? It should be about $30! Get the serial number off the carb and try a NAPA auto parts store. It's actually a Carter AFB carb that Merc painted black, now rebadged as an Edelbrock. They've been around since the early 60s so parts/rebuild kits are not a problem to find. It comes with instructions that are very easy to follow.
