Default Gravely Model LI 1959 Vintage Carb Issue

Greetings all
A first time post in this section of the Stak.
I have a Gravely LI with a zenith carb. It is in need of a rebuild kit for the carb and I have no idea where to locate parts for this beast.

Any suggestions would be greatly appreciated!

You will find them to be excellent to deal with.
Also check McDonald Carb; an advertiser here on the Stack.

These carbs are very simple, but you really need to completely disassemble them and clean out every passage. I have found the area behind the main jet that feeds up to the idle needle to be a bad location for sludge buildup (won't have a clean idle if this is plugged). Do not try and take out all the little jets; too easy to wreck them. Usually the main jet will come out without much trouble.
Get a gallon can of the real carb cleaner w/ strainer at you local parts place (a little expensive but worth it) and let the main body parts soak at least 24 hours. I then clean the parts under running warm water w/ a mild detergent and air dry w/ a blow gun. And blow out all the passages too. If you have a torch tip cleaner you can run the correctly sized cleaner through the open ports. Just don't get too aggressive around any of the jets or orifices. You just want to breakup the carbon and dried up gas deposits. Do not remove any metal.
Done correctly these carbs on the Gravely T-head run very well.

Thank you miltruck..


Back in my car days I used to do a lot of automotive carb rebuilds till the units got so complex that rebuilding them became prohibitive.

I do have a wire set that I used to chase jets and passage ways.
When I took mine off this weekend to see why it would not run going up hill, I saw some contamination and crud.


I had a can of carb cleaner and did some basic cleaning to get the carb back to functionality.
The gasket between the two halves is so dry and brittle I really thought it would not seal back up.
Surprisingly so it did and the old girl ran well for the rest of the day.
I am going to order a rebuild kit and do a complete clean up and replacement of the gaskets, needle and seat and generally make it happy again.
