Weber rebuilding and restoration

Weber rebuilding and restoration

From basic troubleshooting to a show quality restoration

In addition to building brand new carburetion systems, I offer full rebuilding and restoration services on Weber carburetion systems. One of the problems with speciality vehicles, unfortunately, is that they tend to sit for long periods of time. If unused for a period of years, the gas left in a carburetor will turn into a varnish. This acts like dried glue, cementing the moving parts, and clogging small orifices. The Weber IDA's and DCOE's use a brass piston for an accelerator pump. This piston rides inside a close-tolerance bore, just like a piston in a cylinder. Sometimes the pump pistons become "welded" in place from the goop. In addition, the passageways inside the carburetors become clogged, especially the ones with the very tiny holes. And all the balls in the check valves become glued in place, so all the check valves won't work anymore. When this happens, the carburetors are useless until they are completely disassembled, cleaned, and re-assembled with fresh parts and gaskets. Then, everything works like new again. Only factory gaskets, rebuild kits, and replacement parts are used. Most Weber carburetors can be completely restored and made to operate like new again, even after 50+ years.

Full rebuilds and restorative work like this are common; you can ship your complete carburetion system for a total rebuild and/or full cosmetic restoration. If you would like a full cosmetic restoration, your carburetion system will look 100% new when you receive it back. The photos above will give you the idea. I've seen the worst there is; nothing scares me.

On full cosmetic restorations, your carburetors' factory hardware is replaced with fresh bits and pieces, and new linkage pieces are installed. All pieces with yellow-zinc plating will be new, and anything that detracts from the carburetors is replaced. Original screws and nuts are also replaced with stainless screws and nuts, so they will remain good-looking over the years.

The shop rate here is $85 per hour. A full cosmetic and functional rebuild on a typical 4-carburetor V8 unit requires about 15 hours, plus parts. As a general rule of thumb, the labor and parts usually come out to be about the same, which usually includes all new linkage. I can scratch-build any linkage system you need from the parts I have on the shelf, so it's a simple procedure to replace whatever you have, and improve it.

If you already own carburetors and/or a manifold, you can send them here to have a system custom built from your existing parts. I will ship you back a unit that runs and looks like a brand new unit.

On the left is what a typical rebuildable unit looks like when they get here. Some are just a box of parts when they arrive. On the right is the same unit after restoration. This is a smallblock Chevy unit from the 80's, rebuilt and customized for Jim Hegland. Manifold has been bright ceramic coated. Click on the image for a better view.


This is a rebuild done on a smallblock Ford. It was a very original unit from the 60's, restored to the customer's specifications. The customer wanted nothing flashy, just for it to look original for his Cobra.

Hands-on tuning of your engine

If you'd like to bring your car to me, I am located near exit 56 on I-95 in Connecticut, about 1-3/4 hours from New York City, about 2 hours from Boston, and 6 hours from Washington DC.

Most tuning jobs can be accomplished in a few hours, but taking all four carburetors apart gets time consuming. Some sessions can take all day. My rate is $85 per hour, the same as for rebuild work.

I don't perform manifold changes or do complete installations, but I will gladly perform the initial start-up and tuning of your system for you as long as it's already mounted on your car and everything has been connected.
