I have an M18 on a Cub Cadet with 710hrs. The engine runs

Customer Question

I have an M18 on a Cub Cadet with 710hrs. The engine runs fine after the first start of the day. Problem is when it sits overnight it wouldn't start in the morning without a shot of starter fluid. I replaced the needle valve in the carb, but didn't help. Any ideals?

Hi my name is ***** ***** welcome to Just Answer , does this have a choke lever on it ?

Customer: replied 8 months ago.
I've tried with chock and without. Doesn't seem to make any difference.
Expert:  Briggs-Fan replied 8 months ago.

Can you get a look into the carb to verify the choke plate is closing when you put it on choke ?

Customer: replied 8 months ago.
I just checked and yes the choke plate opens and closes as it should.
Expert:  Briggs-Fan replied 8 months ago.

Is it idling and running smoothly ?

Customer: replied 8 months ago.
Runs and idles smooth and starts right up without chock after the first start of the day.
Expert:  Briggs-Fan replied 8 months ago.

Even if it sits for hours inbetween runs ? . It will restart without choke ?

Customer: replied 8 months ago.
After 4 or 5 hrs. of sitting it requires a little choke. When it sits overnight app 12 plus hrs. It does not want to start. Turns over good.

It doesn't sound like a carburetor issue , I'm wondering if the valves are slightly out of adjustment

Customer: replied 8 months ago.
I can have them checked. Also though about changing the plugs although they look good. I just bought this machine about a month ago.
