Holley 6100 series list. We received this carburetor for a rebuild after the owner said it just dumps fuel.

This carburetor has been sitting for a little while too.

We can rebuild just about any carburetor. 

 This carburetor is off a mid 70’s Dodge 413 powered motorhome. 

The factory stamp is still visible on the front of the bowl.

 Carburetor bowls and metering blocks.

We replaced both the primary and secondary floats plus the fuel valves and all hardware.

This carburetor has been sitting with fuel in it for a while 

 It obvious this power valve is blown out.

We double checked, and yes it will not hold vacuum.

We replaced it with a new one with the same vacuum rating.

When the rubber diaphragm in the power valve ruptures, the carburetor will run rich at idle up until the engine vacuum falls below the power valve rating.

 Secondary float bowl.

Similar to the front fuel bowl, but has a different float.

A good soaking in the carburetor cleaner bucket will have them looking like new!

 Finished Holley carburetor.

We pressurize all our  carburetor rebuilds to check for leaks.

We also checked the float levels and readjusted them before the customer received it back.
