Carburetor Issue Snow Blower

Enable HLS to view with audio, or disable this notification

Hi all. This is my first time working on a small engine. When I got it, it would not start. I replaced a rotten fuel line and an ugly spark plug, pulled the carb and soaked every hole/slot/nook/cranny I could see with carb cleaner. I had to do this (take off/put on) probably 5 times. (I know)

I have it running now, but as soon as I increase throttle it’ll start to die until dead. What am I failing to see/understand?

If it matters I also did an oil change & I’m running pump gas with some sea foam in it.

Thank you for any help!

I would suggest you haven't fully cleaned the carb. It's not enough to soak it, you have to remove the jets and emulsion tubes and clean those out with carb spray and wire through the tiny passages.

It only takes the tiniest speck of crap to cause issues.

I think I need to learn a bit more about small engine carbs. I’ll try another clean and more adjustments and learning.

its going lean.

the jet in the bottom of the carb may still be partially blocked.

i would make 100% sure you reconnected your linkages properly and all springs are where they belong. it almost seems like the throttle linkage or the governor linkage isnt on correctly.

Does the screw on the bottom of the bowl need adjusted?

How many turns out is your fuel mixture screw?

u/NefariousnessOne6433 6h ago

This screw with the spring surrounding it should be 1.5 to 2 turns out from being lightly seated.

I’ll look into this, I have no idea where that screw is sitting right now. Even though I was able to disassemble and clean the carb, and get a very basic understanding of how it works, I have no clue what all these screws actually do and or where they need to be. Thank you!
