Good evening, have you checked the float bowl to see if it may have arer in it? When was the mower last run? Do you have fuel getting to the carburetor in quantity through the fuel filter?

Expert:  Curtis B. replied 12 months ago.

This engine has an electric solenoid, that can be screwed from the carburetor bowl to drain it.

Expert:  Curtis B. replied 12 months ago.

With it running only with choke on, you are starving for fuel. It is not getting through the main jet into the cylinders. This electric solenoid can be stick, it does plug the main jet, and has to open when key is turned on!

Customer: replied 12 months ago.
it appears there is sufficient fuel in the lines. I will remove the solenoid and drain the bowl. and go from there. as I recall solenoid removal requires a non standard size... kind of a pain!
Expert:  Curtis B. replied 12 months ago.

Is the fuel solenoid clicking when key is turned on? Does it have 12 volts to it when key is on?

Customer: replied 12 months ago.
Good question let's check, yes the solenoid appears to be functional
Expert:  Curtis B. replied 12 months ago.

OK, when did it last run? It may need a carburetor cleaning.

Customer: replied 12 months ago.
I start it with the choke when I release the choke it revs to where you would expect then fluctuates up and down
Customer: replied 12 months ago.
A few weeks ago, you could be right, but I just serviced the carb last fall (you helped me sort out an issue at that time and I cleaned the carb then)
Expert:  Curtis B. replied 12 months ago.

I understood it died when choke was removed?

Customer: replied 12 months ago.
ultimately it dies after a bit of time (less than 1 min)
Expert:  Curtis B. replied 12 months ago.

OK> drain the carb and go from there.

Customer: replied 12 months ago.
Sounds like a plan
Expert:  Curtis B. replied 12 months ago.

OK let me know.

Customer: replied 12 months ago.
Cleaned the carb and it seems to be good
Customer: replied 12 months ago.
Well it ran normally for ten min then started to struggle and only got it back up to the house by feathering the choke... Uggg
Expert:  Curtis B. replied 12 months ago.

Did you find any debris in carb? Was solenoid working correctly? Needle valve passage from the inlet to the bowl may be restricted.

Customer: replied 12 months ago.
Ok will tear it apart again in the am and check the needle valves there was not any debris in the carb
Expert:  Curtis B. replied 12 months ago.

OK>

Customer: replied 12 months ago.
Hi Curtis, I tore the carb apart again and shot all the raceways and ports with carb cleaner. Seems like its clean, but same as before, it ran good for 10 min or so then back to the same issue.
Expert:  Curtis B. replied 12 months ago.

Is the electric solenoid in the side of the bowl, where you could remove it and plug the hole for test. Test with it removed!

Expert:  Curtis B. replied 12 months ago.

Thanks! Check the suction from the tank to the fuel pump!

Customer: replied 12 months ago.
Can I do that by removing the fuel line from the tank side of the fuel pump?
Expert:  Curtis B. replied 12 months ago.

Yes, you could, put line in a fuel container.
