Tecumseh LEV 100 carb problems??

I have a Tecumseh LEV 100 Spec. 338026F with a carb that has the number 5234 A1E stamped on the carb itself.
My problem is that this thing sat in my garage for 3 years and was not used nor winterized so even though the fuel leaked out of the bowl from a bad washer on the nut on the bottom of the bowl it was still gummed up when I took it off and gave it the once over.
I bought a rebuild kit for it and replaced the needle and seat, the two "o" rings in the emmulsion tube and put on the new float bowl gasket and replaced that leaky fiber washer for the bowl nut. At first the float stuck open and I was getting gas blowing out of the muffler. Took it off again, cleaned it really good again and reinstalled. The float fills up but has no leaks and all is sound but it will not run. I can spray starting fluid in and it runs for 3 seconds, the throttle moves via the governor, then it dies. I have primed 3 times per instructions but never get it to run.

Local shop says they can use some ultrasound thing to immerse the carb in and clean it out for $25. Is it worth that, could there be some crud my carb spray is not getting too? Or is there an easier solution? I have changed the oil again from the previous flooding due to stuck open carb float. Could the primer bulb cause this problem?

I am at a loss on this. All seems clean and well, bowl fills but she will not run once it burns off starting fluid. I am leaving the air filter housing off and spraying fluid straight into the throat.

Thanks all for any insight, I have read and read all I could on here but nothing is helping.

for $25 the ultrasonic cleaning is worth it. First, check the holes in the bowl bolt. There is a real tiny hole in the threads that many guys miss. For the cost of a ne float, you might want to buy a new one as Tecumsehs have a problem with microscopic pin holes in them causing them to become sinkers instead of floats.

 

Thanks for the reply Indypower. The float is good, it past the floating in water test but since I will have the bowl off again I will replace it. Will the ultrasonic cleaning clean the hole that might be clogged in the main jet or will I need to buy a new bolt for that after the cleaning? Guess the ultrasonic breaks all that stuff up into tiny pieces and lets it move on out? they say that $25 covers a basic bench test too.

Are you referring to the bolt that holds the bowl on with two holes in the bottom threads? Guess the hole is up top and gets gummed up?

Thanks for your help,

Check the tiny hole at the top of the picture in the link below, I use the wire frow a twist tie to clean it. Have a good one. Geo

Looks like we both got here at the same time. Have a good one. Geo

Thanks for the photos guys.
I remember cleaning that top hole but I had a few strands of speaker wire wound together and when I pushed it through it did not come out the other side but seemd to go up the side wall or so I thought. Should it go straight through?? Could that keep it from starting up and running entirely?? If so I am guessing a new one would fix me right up?

I went ahead and had the Carb cleaned ultrasonically and I am pleased to report that after taking 10 minutes to put it back on the mower ran on its own for a couple of minutes. I bent the governor wire and it binds a bit but it was getting dark soI will straighten that in the morning. It was keeping it from revving evenly. I think once I straighten it and get the air filter on all will be well. The muffler was smoking a bit but it has not run in 3 years so who knows what is burning off of it.

While they had the carb they put new welch plugs in and replaced the fuel line. Said the plugs were pretty rusty. I hope to mow the entire yard tomorrow.

Thanks for the tips,
Rob
