Then take a pin and enlarge the hole so you can drain it while applying heat from the hair dryer.
Ya don't wanna use an open flame as it is after all, flammable fuel inside.
now when it cools solder up the pin hole with a soldering gun or iron and all is well.
BTDT multiple times over my many years.
Never had one I couldn't fix  |
First off ol'George
Got the carb back together and running good as before -- finished a few cuts and got her back in the shed -- forcast calls for rain and I really don't like leaving her out in the rain...
Lessons learned:
Heating the carb up did indeed reveal the location of the leak with a sudden spew... The leak was on the assembly seam...
My Horror Fright heat gun even set to low is hot enough to melt the solder! Would not have guessed that. Since it's blowing the flammable vapor away from it's hot nozzle the fire hazard is maybe less...? It's still real -- plan accordingly...
My first attempt I suspect I got the float too hot or there was still some gas inside but it blew out the solder before cooling...
Now I felt like I'd be chasing the leak like patching a radiator...
Dried it out again for longer with lower heat -- couldn't detect a leak but...
I used a butane pin torch and plumbers 50/50 solder. I think I sealed it up well.
the test would be to sink it in a jar of gas for a few days and see if it came out dry but like I said, I wanted to move the tractor out of the weather...
I'll pull it off again in a few weeks and give it a shake to see if it's still dry inside...
