I put a carb kit in the k321 including a new gasket for the fitting on the bottom of the float bowl. I cleaned the fitting and bowl but it still seeped fuel afterwards. I removed the bowl again and figured the problem was the bowl surface was rough where the gasket had to make a seal. So, how do I smooth that out? I took a piece of 400 grit and a 5/8" center punch. I placed the top of the punch on the paper and cut slits outwards every 30 deg. or so. That left me with a 5/8" circle of paper that I could tape to the punch by folding the slitted portions over the shaft. Below is a picture of the end of the punch with the 400grit taped on. I then put the punch in the drill press and gently smoothed the area around the hole in the bowl until I had a shiny smooth surface to make a good seal. It worked.

Necessity is the mother of invention. Leaky gaskets are the cousin of blue-goo.

Good job usin your noodle! Did it stay on alright, or did you fight it?

Whats Blu goo? If you mean the sandpaper, it stayed on the punch no problem and stayed centred without any fuss. It didn't take much pressure. The bowl is aluminium so you have to go easy. There are so many problems coming up as I work my way through the tractor that it was nice to stop a leak with an easy fix like this versus buying a new bowl which I would have to mail order as no one stocks K series parts locally.

Whats Blu goo?


I was meaning that most guys would use 6b sealant or whatever would hold up under gas. Blue Goo is a generic term for 6b form a gasket around here. Figured it was a universal term... Sorry, LOL

How about the term " blue goo bandit " when you take something apart and find the person before you used a whole tube trying to mask the leak, missing gaskets , cracked part , the list goes on and on :wallbanging:

Guess I forgot to hit the button on my reply. I think you have a neat idea there. With a little coarser grit, you could use something like this for cleaning tight places for paint and such. Put a little spray glue on the back of the sandpaper and stick it to your punch. Thanks for the idea.

Thanks Kenny for expanding on what I did by using the spray adhesive. I have never heard of blue goo up here in Canada. There is probably a version of it sold here. Blu Goo Bandit- I like it!! It's amazing how a small leak like that will smell up your garage. I could notice it was gone this morning. The 2320 is an oil burner so I am not used to gas in the garage.

Brian, that's how ideas are started. Some one comes up with a solution for their problem, some one else takes it further. But i will keep this in mind for getting to hard to reach areas. Keep posting these neat little things. Hope things are going your way and have a goodun.

Never heard of that either. I'll have to see what the local name is for this sealant or glue or goo or whatever!!
