Threads aren’t too bad but aren’t good, I want to keep an oem carb so I’m not open to amazon 30 dollar replacements. I’m looking for somewhere I can send it to someone who know what they’re doing and how to helicoil it properly, or at least some advice. I’m in south western michigan if there’s any shops around. Thanks you guys.

There are several on the forum that can do it. When you factor in mailing both ways (about $15 each way) and some bucks for time and labor, it might be cheaper to see if a local machine shop would do it for you. The threads are 1/2-20. Unfortunately, a 1/4 NPT barbed fitting for a rubber line is often used that strips the threads. You might try chasing the threads if you have a plug or bottoming tap and see how they turn out.

i will look into some shops around me but could you let me know how to get in contact with someone on here. I‘m willing to pay for something done right.
 
IF you can hold out until the end of May I would suggest you visit the CubFest near Cincinnati. Not only would you get it repaired for almost free, you will also meet many of the members here and learn much about Cubs. Most attendees spend both days here. www.barnyardbash.com
 
Bob is reading this post since he already replied to you. I'm sure he will be replying to you shortly.

Here is my advice since you’re asking. Thread Teflon tape the inlet nipple threads and put it back together. It will hold fine. But before you do, spray that screen and threads good with carburator cleaner. When over wintering the tractor put some fuel stabilizer in the tank and run tractor enough it gets in carb too.

Welcome to the forum! If you're inclined to fix it yourself, go to a hardware store and purchase a 5/16 brass compression union fitting and use a 1/2 x 20 die nut to rethread one end of it to fit into the carb fuel inlet. Clean everything with alcohol to remove any fuel/oil residue and lightly coat the threads of the rethreaded end of the union with JB WELD, install it in the carb, let it cure per label directions then connect the fuel line with the ferrule and compression nut to the other side of the union. It'll cost you less than $5 and be a permanent fix. Works the same for the sediment bowl threads also. BTDT quite a few times. Stan
