Gen won’t run!

[gmann32]

I have a 2004 Lexington by forest river! MicroQuiet 4000 generator! Had set for a year and did not run gen! I removed carb and cleaned! Now I can get it started by holding the choke on until it starts and then open it a very little bit! It will run like that for 3 or 4 minutes and then stall! I get a code of 3-3 and then a 1-4 code! Is it the carb and does anyone know the part number for the carb? The carb had some pretty nasty green stuff in it!
Model number on gen is 4KYFA26100K
SN is I060973054!
Any help will be greatly appreciated! Thanking you all in advance!

Hello, did you change filter? Also premium or hi test gas often cleans things out quickly. I have done this with my generator on occasion.

I took fuel line off and put it in a gal of premium and added a half a can of sea foam! Still won’t keep running!

Carb may need a more thorough cleaning. Get into the jets, float, even the intake manifold may need cleaned. If you get it back running, try to use ethanol free gas in it. If that's not an option, at least make sure the fuel is treated with stabil or something similar. If the gen has it's own battery for starting, make sure it's still good. A bad battery can rob power from a small motor's spark causing it not to fire properly as well.
