I got Jake this Spring. It came with a straight pipe and remnants of a muffler. Very loud. After trying to find a muffler to fit it with no luck, I decided to make one. I started with a muffler off a B&S 15HP OHV engine. This had something rattling around inside, so I took it apart to investigate. Found the guts had fallen into several pieces. After a little trimming here and there, I came up with a new piece for the inside. I opened the holes up to match closer to the Kohler K301 exhaust. Found a piece of auto exhaust for a new inlet pipe. It sits further out than a stock muffler, but it has a longer body and this also gives me good access to the dipstick.

Here's a pic from when I got it.

Here's the muffler pics.

I noticed there was gas seepage at the bottom of the tank.Took it off and after some cleaning, found several issues. Now, to fix this. Not sure whether to go get some .023 wire and weld it, or to use a fuel tank repair kit on it.

It's much quieter! Now to fix the gas tank. Then on to other things that need a little TLC.

Kenny, best way to fix metal fuel tanks o have found it to solder them. And if the metal is gone or hole too large, you can patch them easy with solder. Just need to use a really good flux and muriatic acid with a brush to clean the metals really good. JUST MAKE SURE YOU WASH EVERYTHING SUPER GOOD AFTER YOUR DONE!!! Or it will be a rust ball in a day or so. Its easy and you can make the solder look like it was welded ;-)

Kenny, what brand and size are the rear tires?

They are 23X10.50-12 Carlisle Tru-Power's. They were on my LGT165, but with the engine down, stuck them on here for now.

Thinking along that line too. The hole is larger now. It is mighty thin and opened more as I cleaned the area. Found 2 more small holes nearby. What flux would be good? Not sure what I can find today! I do have some silver solder too.

Those are pretty noisy and I didn't want to try taking the 'stock' pipe off the engine. The bolts there are very rusty.

Nice work Kenny. The way you got it it looks more like a loudener than a muffler. It must have blatted out quite a racket like that.

JB weld also works well for fixing holes in fuel tanks.

OK Kenny here is the liquid flux Iuse the paste is of the same brand. Dont use silver solder it needs to be too hot and will warp the dickens out of it.

Here is what it looks like now after cleaning the area. The hole is pretty big!

I think you could still solder that. I agree silver solder needs to get hotter & I have used muriatic acid many times soldering & I like it. As mentioned clean it good, don't get it too hot & don't hang your head over the fumes, then clean it good again & prime. Jr weld would be a good alternative as well. It looks good how you brought it out with the auto pipe.

Tried soldering. That was a no-go as my little iron wasn't up to the task. Mapp gas was too much heat. Ended up welding the best I could, then JB Weld to stop the pin holes. If someone has a decent tank they want to part with, PM me!
