I have a Holley #3310 750cfm that I need to wrap up and store away as I will not be using it for a while. Once I drain the gas, is there anything I can flush through the carburetor to keep any old gas from gumming it up once it dries? I don't wanna have to tear it apart again to rebuild it in case I need it in a pinch.....
Sta-bil. Seafoam. Any storage fluid. fill it up and pump it through.
I had some gas go bad and shellac up in a marine quadrajet. The carb's not made anymore. My rebuild was $800, 5 years ago because they had to remove the lead plugs and get into the throttle body part of the carb to unplug it. I hadn't stored it with storage fluid. I am passing on what this speed shop told me.
If you add Sta-bil to gas and run engine a few minutes to get the stabilizer through out.It works amazingly well for long term storage
I'd blow it dry and blow it out with compressed air. Do not blow compressed air into any of the diaphragms (choke pull offs and dashpots). The residue left behind by the evaporated fuel is what leaves behind the sticky stuff. Sha-bill is great stuff if the fuel tank is full and you add it to the tank and then run the engine to get it into the carburetor, but long term storage will still lead to the float bowl evaporating dry. sta-bill is good (seasonal), but not intended for multi-year storage.
