Install a 1/4 inch right angle fuel shutoff and your problem will be solved.you can replace the needle and seat too but try the shutoff valve first and see what happens.Thank you for cleaning up your mower.gook and grime retains heat and warps the carb body

Thanks. turfboy1997 also mentioned adding a fuel shutoff, could either of you give me an idea of what I'd be looking for and how I would go about installing it? Since dirt and grime act as an insulator I can see how it would hinder the cooling of the mower but I had no idea it could warp the carb, I would've cleaned it sooner but I didn't have any idea it was like that.

look on ebay for a 1/4 inch right angle fuel shut off valve they are about 4 bucks.drain the fuel tank and cut the fuel line right where the bend is then snip off another 1/4 inch piece of the line its pretty strait forward from there hold the valve up to the line to make sure you cut it in the right spot and have the valve positioned where its easy to operate.lawnboy2 002.jpg

Thanks. I'm going out tomorrow, so I'm going to see what I can find at Home Depot or Menards (we don't have a Lowes). Now that I know what I'm looking for if I can't find anything locally I'll get something on eBay.

These little fuel shut-off valves can be found at almost ALL hardware stores particularly those that have the ACE or TruValue franchise, as well as auto-parts stores. Many auto parts stores have a small section of lawnmower tune-up parts, which include shut-off valves.

Thanks. Well, I looked at Home Depot and Menards today and the only thing that both sold was a Universal Gas Shut off Valve kit made by Arnold. It included a straight shut off valve as well as a length of hose and 2 clamps. Would this work as well as the right angle variety? Do I need the hose and clamps as well? I can get a right angle one without the hose and clamps on eBay if that's better and I don't need the additional parts.

Either one will work fine. It's always a good idea to use fresh fuel line when replacing anything.

Thanks. If I replace the fuel line would I need 2 additional clamps, for the connection at the fuel tank and the carburetor as well?

When fuel line is new, and sized correctly, on a gravity feed system like the Lawnboy or other push mowers have, generally it is tight enough to not need clamps, but as the fuel line ages, it can swell, and clamps might be needed to ensure a drip-proof seal.

Thanks. I think I discovered something that may be a problem with using the shut-off kit. When I looked at the kits yesterday I noticed that they were 1/4" ID, well, I looked up the actual Lawn-Boy fuel line #612782 and according to the pic on this parts site it's 3/16" ID (I think). If that's the case wouldn't that make the shutoff from the kit difficult to install with the existing fuel line or make the new fuel line too big to fit snugly on the fuel tank and carburetor nipples?
