Cub Cadet Push Mower Will Not Start

ProMower · Mar 8, 2017

Hi All,

I have a Cub Cadet push mower I am working on. I am experienced, but stuck on this problem. CDN model # 11A 18M7596

I have a brand new replacement carb, good gas, good plug, and it will not start. It will start for a few seconds if I spray quick start in. It has fuel, the bowl is full of fuel. Gas flows freely to the carb. It has an auto choke system, where the choke is on by default and comes off when the motor gets up to speed.

Any ideas? Thanks!!!

Modern fuels are conductive at compression pressures so once they get wet with fuel they will spark all day outside the engine but not inside.
Cleaning a modern spark plug is by burning the deposits off.
Sometimes a bad plug can be resurected by putting it into a hot engine.

I got another one just like it, going to figure it out tommorow.

I think fresh gas even if the gas looks ok. The other part I found was, the auto choke needs the air filter in place to have enough choke to start. Since I am always testing without the air filter, this kind of tricked me up.
