A while back, I verbally described my method of testing floats for leaks. There were some questions, so tonight I had a chance to work on one.

Testing and potential repair. Won't know until I can get a couple of minutes to reassemble the carb.

Great job on the fix, Alan! The video will be a good tool for folks! This going in the Tech Wiki?

Well done Alan! It's the changing temperature of the brass that heats the air and causes the pressure to increase in the float. If you were to heatsink the float to keep it's temp. relatively constant while soldering you should get rid of the problem. If there are still gasoline vapours in the float that will make the problem worse. Very nice demonstration.

Very cool Alan, I had attempted that kind of repair in the past and could not get past the inside of the float pressurizing when heat was applied. That will be next on my list of things to do. What type of solder are you using? Thanks Kelly

Good old fashioned 60/40 rosin core. Small enough to be manageable on a project like this.
I would say I had that cube on there for 10-15 seconds before I got the tip and the solder on the float.
A smaller tip like this Weller has is a much better choice IMHO than a trigger gun style.

Ha! Better than fella on the PK list who was trying to fix one with a torch!  They told him AFTER, NOt a torch, but sold iron! Was an odd posting hearing his troubles, but kinda chuckled about it too.

I have used copper foil / ribbon to cover larger holes.  You can buy it at any stained glass shop.

Alen, you have a very handsome speaking voice. You could hire out to the others of us making videos.

Nice video Alan. You had me a little worried at first though, with the gasoline seeping out of the float, while laying right next to an open flame gas stove burner. Glad it worked out for you, and Thankful for the tip! :thumbs:

I probably should have mentioned the fire extinguisher in the cabinet next to the stove. Right on about the gas and open flame, thanks for reminding me.

I've done this before using a heat sink & getting the little hole sealed just in time before it blows. Using the ice is a good idea, I think this would give you more time to seal the last hole. Good job on the video too.  :thumbs:

A follow up: the carb that this went back into runs flawlessly. I was about ready to throw the whole thing into the scrap, but it starts easy, runs great, and the mower is a winner!
