My intial attempt at cleaning out the tank wasn't getting me anywhere, so I gave this stuff a try. Very impressed at how well it cleaned up!

The kit to rebuild the carb and fuel tap arrived today. With the carb fully disassembled and cleaned, putting it back together was far less daunting than I was expecting. Helping the situation, the seller of the kit includes an instruction sheet. In my case, I didn't need to make an adjustment to the float level.

Next, the fuel tap. The carb kit includes two replacement o-rings for the inner slide, the originals were hard as a rock.

New o-rings installed, the slide was then reinserted into the brass body, followed by the holding screw. Initially, the new o-rings make the movement very tight, but with a bit of working, they free up and begin to function properly.

After rinsing out the tank with carb spray, I then reinstalled the tap, which are a tapered thread and go in very tight. Some fuel in the tank verified no leaks from the fitting or past the o-rings. Sucess!

I then connected the new fuel line included in the kit, turned on the tap and filled the carburetor bowel with fuel. I even gave the tickler and tickle to verify it was working. Again, success! No leaks.

Super pleased to get this step completed, let's just hope it works as it should.
