Thanks rokblok!
Can you soak the whole carb in there prior to disassembly or piece by piece?

I suggest piece by piece. That way it has a chance to get into the vacuum passages and such. The basket has a pretty fine screen so nothing should fall out. I do all the itty bitty things by hand anyway... But all the jets, bowls, venturis, body, anything metal can be dipped overnight or a couple days.

I just disassemble everything and put it in the basket and let it soak.

Great Resource

Glad I found this thread. Helped me with my carb rebuild. I made the mistake of sending it initially to a rebuilder called Carb Junkys in Atlanta, GA. Big mistake. Ended up having to rebuild it again.

That is the Power Piston. The Power Piston acts against the Power Valve at the bottom of the float bowl.






The main Accelerator Pump (there's the main pump and then the secondary pump) is on the outside of the carburetor.






The Auxiliary Accelerator Pump is on the opposite side of the carburetor.

Lower Butterflies on 85 carb Sticking

Is there a way to get the lower butterflies off of the carb. I have that lower section soaking for 48 hours and the lower large butterfly is real hard to move. Everything else looks clean and ready to go but this thing is really gummed up.
Any help would be great. Thanks

Replace POWER VALVE

With engine off, if your float reservoir is leaking fuel into intake manifold, replace POWER VALVE. PV leaks into the manifold causing a very rich condition at idle and low speed. Replace Power Valve.

After full carb rebuild on ’85 22R Carb; with engine off, my ‘85 Carb float reservoir leaks fuel into intake manifold. Does this seem like jet needle not seating or perhaps power valve leak?

This is a very common occurrence after a the carburetor has been rebuilt.


When I did mine, I replaced the Power Valve, yet is still leaked. I then cut off the metal plunger only portion that actuates the Power Valve, this pushes the valve open. It still leaked.


I never was able to solve the carburetor leak.
