Fuel would seem to gather at the bottom of the fuel bowl (keep in mind, the picture is upside down, the fuel bowl hangs below the carburetor) and it would drip about one drop every ten seconds as long as there was fuel in the carb. It's not terribly difficult and as long as the carb is off the engine anyway you may as well spend $11 and replace the little seals and needles that wear out.ĭid the work, put it back together, and it still leaked. I knew I'd have to take the carburetor off to fix this leak, so while I was at it I decided to clean it out and do the overhaul kit. Since I don't like to drip gasoline (and more important, I don't like to drop toxic MTBE) all over the place, I wanted to fix this leak as quickly as possible. I normally shut off the fuel at the valve and let it run until the carb is empty when I put it away to help keep the carb clean. It didn't leak much, but that's because a long time ago I'd added a cheap in-line fuel cut-off valve that I use when the unit is not in operation. Starting this fall I've noticed a small amount of fuel leakage and it's been running rough. Once or twice it was just accumulated corrosion and there's always a little dirt.
3.5 HP TECUMSEH ENGINE NEEDLE SETTING FULL
One year the whole thing was full of blue crystalline material. Over the years, I've had to tear down and clean out the carburetor a couple of times due to the weird crap we've got in gasoline now. I have a Tecumseh 8hp engine on an MTD snow thrower from about 1993 (link to rebuilding project). I wish I'd kept my old MTD mower instead of replacing it with a Deere, but that's another story. They find simpler ways to get the job done, and often they're really great solutions. They don't take an expensive product and cheapen it with bad parts. They tend to be on the lower end of the price scale, but I find their designs are wonderfully innovative and simplified. Let me be clear first - I like MTD products. I found very little helpful information on this problem when I searched, so I'm writing it up. In that spirit, here's a similar article for owners of Tecumseh engines on snow throwers (aka snowblowers) and lawn mowers. It's turned out to be one of the most appreciated articles on the site, and I still get "thank you" notes on it regularly.

Eighteen months ago I wrote a little article about how to adjust the brakes on a lawn tractor because I couldn't find the information myself when I searched.
