After I posted this morning, was there any point in this whole not running issue where fuel was pouring out of the carb because of a defective needle? If not, then I don't know if I would risk changing the needle and seat (unless the new needle is viton tipped) and ruining a pair of floats on a system that worked before. I see Rich and I are in agreement to heat the brass extension.

i got everything done... i put the float in a 5 gallon bucket and heated the extension... as for the seat it is an all metal needle... and i went and put it on the carb and everything looks good so i am just waiting to find an idle jet... i called my cat dealer again to findout that they dont have a micro fish for the 22... so there getting one for it on tuesday... so hopefully they can help me find one...

well ok i found the idle jet size is 18 and the cat # is 1f2144 as well as the zenith # is c54-1... i don't know were to look now... my cat delar says that cat no longer sells verry much for the 22 including the idle jet...

From the photo but a Ford Model A had a similiar type of jet in its Zenith. Google "Sacramento Ford" as they specailize in vintage cars and maybe can help you.

I believe I mentioned before???

Try these guys-they are the go-to for antique puller carbs, maybe they can help on a Cat too...

Edit-guess it would help if I posted the link...

ok i ordered one from Sacramento Ford i beleive that it will work it looks the same so all i can do is wait till it arrives... the only other things i can think of other than that link is to go to other cat forums and see if anyone else has an old one that i can buy off them...

ok i ordered the idle jet and i got it and it had too small of threads so now i have no idea what to do...

I was thinking and looking at the original photo of the rotted off needle. I was tempted to tell you to drlli out the base enough to flip the tube over and silver solder it in. Looking at the rot on the tube I figured it wouldn't be a good idea. What are the thread size differences between the 2 parts?
Are the rest of the dimensions the same?

the end length is the same so does anyone have a spare 22 with the zenith 7070a carb on it??? if so i will pay if reasonable... aka >$60 i really need to get it running for my grandpa... thanks

Hey LCM,

It's hard to tell from the picture, but could you remove the tube from the new jet and solder it into the body of the old one? Is the thread size standard or is it some "funky oddball" thread? Is there enough difference in the thread size to make an adapter (take a screw that will fit into the carb, drill & tap it to fit the new jet and cut it off to length)?

There are many ways to make things work on these old machines. As a Machinist I have made or modified lot's of carburetor parts (where I work when somebody comes in off the street with a carburetor repair the boss always gives me the job to work on). If worse comes to worse you could send me your two jets and I'll see what I can do to make it work & send them back.
