Default CAN NOT TIGHTEN CARBURETOR

I can not tighten the carb on my Super Tigre .45, the nut keeps going in a circle and does not tighten. Aparently I will have to replace the retaining bolt and nut, so does anyone know where I can get one? Does Towerhobbies supply them?

Same exact thing happened to my Thunder Tiger Pro 46. I returned the whole engine to Tower since it was new. In your case, contact Super tigre for replacement parts.

You will need

First choice would be buying it from towerhobbies. I am a long-time customer of theirs and have spent 1000s of $$$$ with them and have always been satisfied.

Here you go buddy

inspect the carb, especially where that retainer preses against the carb body to make sure it's not dented in. That was case with my carb body and not even a new retainer was working. but at 95 cents, worth a shot.

Thank you so much n19htmare. Will check the carb for dents when I take the retainer out.

Actually, you merely stripped the soft brass nut.

You can buy these seperately too.

Be VERY careful when you tighten the new one down, it merely needs to go a bit tight to hold the carb. Apply threadlock too.

If that's the case does anyone know the size of the nut? And if it is fine thread or metric or anything?

While I agree that it's probably the nut being stripped (and you can check that), it could be the carb being dented or deformed if the engine was crashed. I've done that trick on more than one small engine in a combat plane.

Since you don't really need much force to hold the carb down, sometimes JB weld applied carefully can be used to give the retainer cam thingie something to bite into.

Edit: I just remembered that I have a TT .46 Pro that was crashed, causing the carb to rock back and actually break the crankcase around where the retainer cam is held. The owner thought the engine was trash and gave it away. I built that area back up with JB Weld, and that engine is still running many many flights later, and the cam still works, even though half the area holding it in is JB weld that I worked into shape and drilled.

Engine has never run. Brand new but stored for over a year.
