FDNY 343 Posted March 8, 2019 Share Posted March 8, 2019 So I've been chasing many Vacuum Leaks on my 1955 B85 Thermadyne Gas motor Fire Engine. I rebuilt a vacuum control diverter valve on the Hale Fire Pump that was so dry rotted and leaking like a sieve, I believe I fixed a Vacuum leak going to the Hydrovac Unit for the brakes. I now think I have a Vacuum leak in the Zenith Carburetor which I believe could be worn Vacuum Pistons of the Governor Throttle or the Vacuum Controlled Pump Piston of the accelerator pump. Either way I guess I have to rebuild the Carb, which leads me to my question... Are there any Complete Rebuild Kits out there? Are there any Rebuilt Carburetors out there? I've been all over the internet and have come up empty, any help would be greatly appreciated. Thanks Jimmy K 1955 Mack B85 Thermadyne Fire Engine Quote Link to comment https://www.bigmacktrucks.com/topic/56060-zenith-29d-series-duplex-carb/ Share on other sites More sharing options...
j hancock Posted March 9, 2019 Share Posted March 9, 2019 I would call or email these folks for Zenith carb needs. http://www.thecarburetorshop.com/ Quote JimIt doesn't cost anything to pay attention.
