Couple things I'm wondering while rebuilding TSX769 carb. On the bowl part there is needle valve and seat. Then a small jet then a hole with no jet. Should I be able to blow air threw this.Also in bottom of bowl the is a small threaded hole should this have a jet. I found one diagram that might show it as power jet?

Looking at diagram again I believe the hole
I'm talking about is fuil passage for idle
system.I can't get any air to blow threw. #
13 on diagram. The threaded hole in bottom
of bowl I think is # 12 on diagram power
jet. If this needs jet what size..thanks

I don't have the same diagram you have, but from the description...

The idle circuit does feed through the small holes beside the venturi, in the bowl section.

One draws fuel up. It gets the fuel through the main jet circuit. Above that passage in the top section is an idle jet.

The other is an air bleed passage, no jet.

The idle mix adjustment is done by metering in more air to lean the mix, less air to enrichen. Thus backing out the mix screw leans, turning it in makes it rich.

Yes, you should be able to blow through all of those passages. I generally don't take the small jets out for fear of breaking the ears off. I like to scrape out the jets with a tiny wire, like you would pluck from a wire brush.

The threaded hole in the bowl is for an optional power valve. If there was nothing there, there likely never was. I've seen pictures of the power valve option, but never a real live one.

Here is some helpful info. It covers several models, be sure you are in the right section.
MS Carb

Ford 801 series ran from 1958 till 1962. In 1963 they came out with the thousand series.
801 is the series number and in that series there is a range of models. 821, 831, 841, 851, 861, 871 and 881. Some did not have PTO or 3 points. The 841 was a 4 speed with non-live PTO. 851 had a 5 speed with non-live PTO. 861 had a 5 speed and had a 2 stage clutch giving it live PTO. The 871 and 881 where the SOS models and had live PTO

The model and serial number are on the left hand side. If you look at the starter and place your left hand on it and your right hand on the clutch pedal and look down you will see 2 bolt holes that go in horizontal. Just above them is the model number and the serial number. It will look sort of like this

841S
*^^*&*^&*

In this case I am going by the 801 I have which is a 841S the S standing for the factory install Sherman combo transmission. The model is 841S but it is still an 801

Always happy to help if and when I can. Does it by chance have shifter handle just forward of the clutch pedal?? If it does then it has a Sherman Aux transmission

Ok so here are a couple of other things for you to check and think about.
#1 does the model number read 841 or does it read 841S?? If it reads 841S it has a factory install Sherman if it only reads 841 then it was a dealer installed one.
#2 put the Sherman in neutral and then pull out to the side with it. If it goes out about 1/2 and inch then pull back/up on it. If it does that then it is a Sherman combo which gives you 3 speeds in the Sherman. Out and up are standard gears as in what it would have with out the Sherman. In and own is low range and in and up high range
