Seems I fix one thing then another thing breaks...it's really getting on my nerves, but still this hobby sticks to me

The engine is a .61 ASP 2 stroke.

I took off my caburator yesterday to put the throttle linkage on...Sorry to those guys who suggested the EZ connector in the "Throttle pushrod" thread. I checked out a couple of other guys setups and 6 out of the 10 guys used a Z bend. So I'm going to try that since it's going to be the easiest now.

Now, I took off the caburator because I couldn't get a proper Z bend onto the carbs side. The carburator has two screws (see picture below where you can see the top one) which tightens it - one at the top and one at the bottom. I took the screws/bolts (I sometimes don't know when to call it which lol - stupid me) out - they were tightened down well. Took the carb off and put on the Z bend. Then came the headache...the bottom screw now tightens a bit, but not that it feels safe - I can ALMOST unscrew it with my fingers, the top however I CAN unscrew with my fingers. I struggled with this for about one hour and gave up. I don't know if the thread was stripped sometime close to the bottom or whether the screws are long enough - since the thread seems to be on the carbs holes, but the screws first have to go through the "carbs mount?" It's not very long screws but they did work up until now.

Is there a trick to this or when the engine start up will the carb get "sucked" tight (putting my hopes on something not realistic here I guess)? I know the 75 I have has one screws which serves as in sort of a clamp to tighten the carb down. My 46 has this same setup as the 61, but they seem tight.

If this is faulty and that the thread has stipped - is there a way to fix this without getting a new carb?

*forgot to add pic*
*and then I add the wrong one to - lol - its too early - now it should be right*
