The Ford Barn

I would like to ask a few Tillotson Crab questions:

What do I clean with
What do I NOT clean with
What do you use for a Plug after having drilled out old ones
I assume that drilling is the way to get the old ones out
Can the Venturi come out or is it a fixed part of the carb
I’m working on one for a fellow, the top of the Ventura has a ½ chip out of the top. It used to run well I’m told, I assume hat it already had the chip as I didn’t see any such broken parts, how bad is this problem?
The body is warped a bit, I’m understand you can bake it with a hose clamp around it to bring is together, What Temp, and how long would you recommend.
Any other advise?

I took easily 2 table spoons worth of caked dust out of this thing.

Pictures of this carb can be seen at: https://www.dropbox.com/sh/j2ayegvik...ytpVUdfBGUoULa

Thank you very much
Ben

It's been awhile since I have had a Model X apart but I seem to remember that chip is for clearance.

Clean with carb cleaner for a light cleaning. Otherwise chem dip for half a day, no longer.

Completely disassemble and clean everything. If the jet in the bottom of the bowl is hard to remove leave it. Be careful not to destroy it.

Don't drill out the plugs.

Venturi does not come out. It will look like it has a broken edge but it's not it's designed that way.

True up the mounting flange using w/d sand paper with a piece of glass and sand it until it's flat.

There will be warping where the two halves go together so use either a thicker gasket or two thin gaskets.

When you mount it to the intake manifold snug it using a thin gasket or no gasket and Yamabond sealant. Thus will keep it from warping. Don't over tighten.

The main jet might be hard to unscrew. Run a tap in it first. When you get it out re tap it all the way. Don't go too far. Make sure you put the small gasket on the main jet when you reinstall it.

Just got done doing mine. Runs great.
