I just wanted to share my dumbass mistake.

I have a set of Keihin PD41A carbs for my bike and the accelerator pump bowl has a crack in the overflow brass tube. I decided to take it upon myself to disassemble it and try to get some solder in there.

Well, come to realize there is a tiny check ball that is held in with a tiny spring and piece of what looks like square plastic that was pressed in to hold it together.

You can probably guess what happened next..I used a propane torch to heat the tube, got the solder on and the heat melted the plastic square fitting.

Now I'm screwed and had to order a whole set of used carbs off ebay for parts. Cost me 200 bucks.

On the bright side, I have more parts! I only hope the accelerator pump bowl doesn't also have a cracked tube...

Don't do what I did...
