Stripped float needle holder hole
« on: June 28, 2018, 02:37:38 pm »
So I was attempting to clean my carbs for the first time.  Everything was going pretty well until the head of the screw holding down the float needle snapped off.  I tried to reverse tap it with a screw extractor but it just got mangled.



I do t even know if it can be retapped with a bigger screw at this point I don’t think the remains of the old screw are completely out.  Do I need to just start looking for a new carb?  Has anyone had this happen?

I once dated a girl that stripped my float needle... but that was different.

It looks awfully thin to re-tap it. If you have dripped and tried to extract it, try putting in a pipe cleaner or very small wire brush into the hole with some lubricant. Turn it counter clockwise and see if you can get what looks like old thread out. If the threads in the carb are still not grabbing, maybe a self tapping metal screw? It will take work to get it into solid metal, but it may save you money.

How did you break the head off anyways? I hope you weren't using power tools... always ends badly IMO.

You can contact Jim French through this forum and send that to him. He can perform miracles with his micro TIG welding and return to you a nearly factory perfect carb body for a fraction of the price of hassling with a replacement.

No power tools just snapped right off, I did use a power drill to try and reverse thread and untap which is definitely when it got mangled
