Question Subaru EA17V cuts out.

Hi, new here. I have a Subaru Electric Start lawn mower with the same engine that is on their powerwashers... an EA175V. If I blow Gumout Carburetor and Choke Cleaner the mower will start, but immediately chokes out as soon as the gumout is used up. I have cleaned the carburetor thoroughly. Still the same problem. I have checked that gas is getting to the carburetor and it is filling up.
Not sure what the problem might be. I do not see a choke anywhere on the engine itself, so I'm not sure how to fix it.

Any ideas? Would be most helpful !
Thanks
Jeff

The parts list shows a choke on the carb, not sure why you don't have one.
Page 36 of the service manual shows the main jet and nozzle holes that HAVE to be clean for the engine to run. Page 37 shows the choke linkage.

Experience is something you don't get until just after you need it.

Thanks. I cleaned the nozzle holes and soaked the disassembled carb in pinesol. It looks very clean after washing and drying. The float seems to have enough play in it. What I did notice however with the choke linkage is that none of the hand levers affected the linkage. (there are 2... 1 has to be closed to start the engine, the other closes to start the self propelling) So I'm not sure that the choke is working properly.

I see in the owners manual that there appears to be TWO different throttle controls for operating the choke. If your sure the carb is clean, then I would guess the choke function is not working correctly. Have you remove the air filter to see if the choke is closed when activated by either of the user manual instructions?

If you removed the carb from the engine to clean it, maybe a piece of linkage was incorrectly installed? Page 6 and 9 show the two different choke/throttle controls.

Hi thanks again. So, when I close the start lever, the "manual" choke on the left side above the fuel valve goes to choke but valve is open only about 1/8 to 1/4. What does not move is the Auto choke, and perhaps that functions when the engine is on. When I manually pull on the auto choke, I can see the choke valve opens completely.

Also, my unit does not have the primer pump bulb. When I look where it would be, there are only 3 holes but nothing in back to create suction, so I suspect it isn't on this model.

I don't hear any sputter at all, so it seems fuel is not getting to the engine. It sound dry when I turn the key.

Thanks for the help. I ended up replacing the carburetor entirely and it works. Apparently no matter how much I cleaned the old one, it didn't help.
