Need help with honda wb20x gasoline water pump throttle and governor springs

I made a post about a water pump that would not run unless the choke was fully on. I never solved that problem so I took it to the service department where I bought it and the service guy was puzzled too so I just decided to use it like it was. It runs.

Anyhow, I have this other honda wb20x, a slightly different model that I did some work on today and got running as a back up, but the governor spring is off and I don't know which holes it connects to. It might be an obvious thing but there are several holes and I just dont know. I said the throttle and governor springs but it's just the governor spring. The throttle lever is not connected to anything.

Here's a link to the manual for this model.

This is a link to the control diagram. It's the #3 spring.

I took it to a friend who used to work on small engines and he put the spring on for me. Still not quite right (runs to slow) but I think I can adjust it.

The engine only running with the choke "on" is possibly a clogged passage or jet within the carburetor.

You say the throttle lever is not connected to anything. That is obviously not correct.

When connecting the linkages keep in mind that the throttle tries to pull the throttle open while the governor works to pull the throttle closed. The instant you start the engine the governor arm will move to pull the throttle closed. The faster the engine turns the harder the governor arm will pull to close the throttle. The throttle tries to pull the throttle open. So, both of them via springs are fighting and balancing each other.

I must have gotten a bad one then if it's a clogged jet because it's a brand new carburetor. Everybody I asked said it was the carburetor. Guess I need to talk to the parts guy about it.
Dont know about the governor spring. A friend hooked it up for me When I said there was nothing connected to the throttle lever I meant there were no springs connected. I knew there should have been, but just didn't know where it went.
Wish I would have spent more time learning about small engines.
Let me ask you this. I have another smaller gas engine that's been backfiring lately (really loud). The other day it backfired once and it died and I took a break and it started up fine. Most of the time it backfires when I turn it off. This has just started the last few days. You think there some big problem? The oil's fine, I replaced the spark plug not that long ago, new air filter etc... and before this it was running great. I did get a little water in the gas tank 4 or 5 days ago but it wasn't running at the time and I turned the gas lever off and siphoned what little gas was in it out and took a rag on a stick and sopped up all the fluid I could see in the tank and put new gas in it. Wonder if any moisture got through and would that cause backfiring?
