It has a techumseh motor model number th139sa 139cc displacement. It is getting spark and I replaced the spark plug with an oe one. The fuel is fresh fuel pre mixed. It is getting both fuel and spark but won't start. I need help as I don't know what could be the problem

Hi,
I show this as a Murray/Scotts made for Home Depot in the Canadian market. Parts breakdown is here:

Owners manual not found.
You say it is fresh mix, but was it dumped of bad mix? Is it a float or diaphragm carb? Any numbers or such on engine?
Peace,
Clarke

The tank was drained and the mix was completely fresh. Carb is a float carb and I cleaned it out as it was plugged. What numbers do you want the ones for the blower or the motor

PS The first and last are different!

OK so I'm still having troubles with the motor. I have tried priming the motor by putting a little bit of fuel into the cylinder but it still won't start. It seems to be flooding the engine and the carb as fuel is spitting out the end of it. One pull on the cord and it seems to flood it. I have adjusted the float and cleaned the carb. It has compression which I have check by plaacing my finger over the sparkplug hole while pulling the cord. Any ideas what I can do next?

The fuel valve is sticking in the carb. You may have to dissassemble and clean.

-or-

You can try a small amount of gas mixed with Seafoam carb cleaner after draining the tank.

FYI:
You can use spray carb cleaner as starting fluid. DO NOT use starting fluid. Gas is Ok, but carb cleaner is better.

You need to use fuel stabilizer like Sta-bil. 20/20 hindsight.

OK where abouts is the fuel valve in the carb

Where abouts is the fuel valve

Hi,
I might point out that the manuals tell you that there is a correct direction for the pointed end of that wire on the inlet needle. It must point toward the air cleaner/air intake.

Fuel needle is #30 on first carb line.

Then engine is there also, but not the SPEC number

OK thanks will let you know if this works

Do you think there is anything else that might cause it to not start
